Ports 1–16 support PoE and PoE+ with a total power budget of190W.• GS324PP. Ports 1–24 support PoE and PoE+ with a total power budget of380W.If the power requirements for the attached powered devices (PDs) exceedthe total power budget of the switch, the PD on the highest-numbered portis disabled to make sure that the PDs connected to the higher-priority, lower-numbered ports are supported first.Just because a PD is listed as an 802.3at PoE powered device does notnecessarily mean that it requires the maximum power limit of the specification.Many PDs require less power, potentially allowing more PoE ports to be activesimultaneously.The following table shows the standard power ranges calculated with themaximum cable length of 328 feet (100 meters).DeviceClassStandard Class Description PowerReserved bythe DevicePowerDelivered tothe Device0PoE and PoE+Default power (full)0.44W0.44W–12.95W1PoE and PoE+Very low power 4.0W0.44W–3.84W2PoE and PoE+Low power7.0W 3.84W–6.49W3PoE and PoE+Mid power15.4W 6.49W–12.95W4PoE+ only High power30.0W12.95W–25.5WIf a device receives insufficient PoE power from the switch, consider using ashorter cable.PoE TroubleshootingHere are some tips for correcting PoE problems that might occur:• If the PoE Max LED is solid amber, disconnect one or more PoE devices toprevent PoE oversubscription.• For each powered device (PD) that is connected to the switch, the associatedPoE LED on the switch lights solid green. If the PoE LED lights solid amber, aPoE fault occurred and PoE halted because of one of the conditions listed inthe following table.PoE Fault Condition Possible SolutionA PoE-related short circuit occurred on the port.The problem is most likely withthe attached PD. Check thecondition of the PD, or restartthe PD by disconnecting andreconnecting the PD.The PoE power demand of the PD exceededthe maximum level that the switch permits. Themaximum level is 15.4 for a PoE connection or30W for a PoE+ connectionThe PoE current on the port exceeded theclassification limit of the PD.The PoE voltage of the port is outside the rangethat the switch permitsRestart the switch to see if thecondition resolves itself.Mount the switch in a rackWe recommend that you use the brackets and screws that came with the switch.1. Attach the mounting brackets to the side of the switch.2. Insert the screws through each bracket and into the bracket mounting holesin the switch.3. Tighten the screws with a No. 1 Phillips screwdriver to secure each bracket.4. Align the mounting holes in the brackets with the holes in the rack, and inserttwo pan-head screws with nylon washers through each bracket and into therack.5. Tighten the screws with a No. 2 Phillips screwdriver to secure mountingbrackets to the rack.。

GWD-TN-24 使用说明

[转帖]倾情奉献: 最新/最全/最完善GWD版本!!!/dispbbs.asp?boardID=34&ID=304220&page=1送给大家一个最新/最全/排版最好/最完善的GWD版本!!!GWD-TN-24 版本说明:1. 关于XY13/天山/涛涛31/CD22/Too-24/GWD-TN-24 的来龙去脉:很多新人对于这些眼花缭乱的版本名字很迷惑, 其实这基本是一系列递进版本. GWD-TN-24 版本来自于这些版本,并尽量剔除了重复的题目.2. GWD-TN-24 的最大特点: 最好的排版!!!GWD-TN-24 是建立在CD22和Too-24版本上的. 其最大的改进就是尽量模拟GMAC的真实考试界面: 所有的字体(Tahoma), 字体大小(9.5), 页间距不要随便改变,现在的格式能保证每行字数与GMAT考试每行字数大致相等。

你可以通过改变word view的百分比来调节相对字体大小 (每个人的屏幕分辨率不同, 百分比不同,可以自己与PPrep进行比较)。

另外原来的GWD阅读句子每行太短, 题目在后面, 让人很不舒服, 这个版本最大改版是把阅读格式改成了左右分列, 符合GMAC的考试习惯, 让大家模考也要有真正考试的感觉!3. GWD-TN-24 题目的具体说明:虽然有24套题, 我更愿意把它分成24=21+3. 因为最后三套的题目只有阅读/逻辑是新的, 语法题目大部分来自Prep1 (SC题目不够了). 所以大家不要把22/23/24留到最后模考. 前21套里面1-13应该是携隐13套, 题目相对有些老, 14-21感觉比较新一些.4. 关于答案:如果最后排版没有差错的话, 答案应该是99%正确的. 再次感谢來自台湾的Tootoo5478, 最终答案是建立在他的Too-24版本上的, 所以"TN版本"的T就是代表Tootoo的. (如果大家发现有错误, 请尽快与我联系).5. 关于下载和密码:设置密码是防止我们的共享被印度人等偷取(已经发现有很多外国人来CD下载并传播了), 我们应该尽量保护自己的资源, 所以请大家转发转载时注意保密.我手头的一些材料基本都传上来了, 受益于CD, 回报于CD, 终于安心做到了. 最后祝大家马到成功!。

This command may either allow the device, after some vendor specified event, to save the device updated attributes to non-volatile memory; or this command may cause the autosave feature to be disabled. The state of the attribute autosave feature, either enabled or disabled, shall be preserved by the device during all power and reset events.A value of zero written by the host into the device’s Count field before issuing this command shall cause this feature to be disabled. Disabling this feature does not preclude the device from saving SMART data to non-volatile memory during some other normal operation (e.g., during a power-on or power-off sequence or during an error recovery sequence).A value of F1h written by the host into the device’s Count field before issuing this command shall cause this feature to be enabled. Any other other non-zero value written by the host into this field before issuing this command is vendor specific. The meaning of any non-zero value written to this field at this time shall be preserved by the device during all power and reset events.SMART SAVE ATTRIBUTE VALUE (B0h/D3h)Saves any modified attribute values.SMART ENABL OPERATIONS (B0h/D8h)Enables the SMART function. This setting is maintained when the power is turned off and then back on. Once the SMART function is enabled, subsequent SMART ENABLE OPERATIONS commands do not affect any parameters.SMART DISABLE OPERATIONS (B0h/D9h)Disables the SMART function. Upon receiving the command, the drive disables all SMART operations. This setting is maintained when the power is turned off and then back on. Once this command has been received, all SMART commands other than SMART ENABLE OPERATIONS are aborted with the Aborted Command error.This command disables all SMART capabilities including any and all timer and event count functions related exclusively to this feature. After command acceptance, this controller will disable all SMART operations. SMART data in no longer be monitored or saved. The state of SMART is preserved across power cycles.Wellcorping Technology Co., Ltd© WELLCORE 2011.

If the Count field is non-zero then the Standby timer shall be enabled. The value in the Count field shall be used to determine the time programmed into the Standby timer. If the Count field is zero then the Standby timer is disabled.STANDBY IMMEDIATE (E0h)This command causes the drive to set BSY, enter the Sleep mode (which corresponds to the ATA “Standby” Mode), clear BSY and return the interrupt immediately.WRITE BUFFER (E8h)This command enables the host to write the contents of one 512-byte block of data to the device’s buffer. The READ BUFFER and WRITE BUFFER commands shall be synchronized within the device such that sequential WRITE BUFFER and READ BUFFER commands access the same bytes within the buffer.WRITE DMA (CAh)Write data to sectors during Ultra DMA and Multiword DMA transfer. Use the SET FEATURES command to specify the mode value.WRITE DMA EXT (35h)48-bit feature set mandatory command. Write data to sectors during Ultra DMA and Multiword DMA transfer. Use the SET FEATURES command to specify the mode value.WRITE DMA FUA EXT (3Dh)48-bit feature set mandatory command. This command provides the same function as the WRITE DMA EXT command except that regardless of whether volatile and/or non-volatile write caching in the device is enabled or not, the user data shall be written to non-volatile media before command completion is reported.WRITE FPDMA QUEUED (61h)NCQ feature set mandatory 48-bit command. This command causes data to be transferred from the host to the device.Wellcorping Technology Co., Ltd© WELLCORE 2011. All rights reserved WRITE LOG EXT (3Fh)This command writes a specified number of 512 byte blocks of data to the specified log.WRITE MULTIPLE (C5h)This command writes the number of logical sectors specified in the Count field. The number of logical sectors per DRQ data block is defined by the content of IDENTIFY DEVICE data word 59. If the number of requested logical sectors is not evenly divisible by the DRQ data block count, as many full blocks as possible are transferred, followed by a final, partial block transfer. The partial block transfer is for n logical sectors, where:n = Remainder (Count / DRQ data block count).Device errors encountered during WRITE MULTIPLE commands are posted after the attempted device write of the DRQ data block or partial DRQ data block is transferred. The command ends with the logical sector in error, even if the error was in the middle of a DRQ data block. Subsequent DRQ data blocks are not transferred in the event of an error.The contents of the Command Structure following the transfer of a DRQ data block that had a logical sector in error are undefined. The host should retry the transfer as individual requests to obtain valid error information. If IDENTIFY DEVICE data word 59 bit 8 is cleared to zero or IDENTIFY DEVICE data word 59 bits (7:0) are set to zero, and a WRITE MULTIPLE command is received by the device, and no successful SET MULTIPLE MODE command has been processed by the device, the device shall return command aborted. A successful SET MULTIPLE MODE command should precede a WRITE MULTIPLE command.WRITE MULTIPLE EXT (39h)48-bit feature set mandatory command. This command is similar to the Write Sectors command. Interrupts are not presented on each sector, but on the transfer of a block which contains the number of sectors defined by Set Multiple command.WRITE MULTIPLE FUA EXT (CEh)48-bit feature set mandatory command. This command provides the same functionality as the WRITE MULTIPLE EXT command except that regardless of whether volatile and/or non-volatile write caching in the device is enabled or not, the user data shall be written to non-volatile media before command completion is reported.WRITE SECTOR(S) (30h/31h)Write data to a specified number of sectors (1 to 256, as specified with the Sector Count register) from the specified address. Specify “00h” to write 256 sectors.WRITE SECTOR(S) EXT (34h)48-bit feature set mandatory command. Write data to a specified number of sectors (1 to 65536, as specified with the Sector Count register) from the specified address. Specify “00h” to write 65536 sectors.WRITE VERIFY (3Ch)This command is similar to the WRITE SECTOR(S) command, except that each sector is verified before the command is completed.Wellcorping Technology Co., Ltd8 NCQNCQ-Native Command QueuingThe WELLCORE W10 Series supports the Native Command Queuing (NCQ) command set, which includes:•READ FPDMA QUEUED•WRITE FPDMA QUEUEDNote:With a maximum queue depth equal to 32.Wellcorping Technology Co., Ltd。

GWD-TN-24

GWD-TN-24 第⼗⼆套详解（11）T-4-Q24~27: T S-7-33～36Until recently, zoologists believed that all species of phocids (true seals), a pin-nipped family, use a different maternal strategyThe maternal strategy evolved by harbor seals may have to do with their small size and the large proportion of their fat stores depleted in lactation.Harbor seals are small compared with other phocids species such as grey seals, all of which are known to fast for the entire lactation period. Studies show that mother seals of these species use respectively 84 percent, 58 percent, and 33 percent of their fat stores during lactation. By comparison, harbor seals use 80 percent of their fat stores in just the first 19 days of lactation, even though they occasionally feed during this period. Since such a large proportion of their fat stores is exhausted despite feeding, mother harbor seals clearly cannot support all of lactation using only energy stored before giving birth. Though smaller than many other phocids, harbor seals are similar in size to most otariids. In addition, there is already some evidence suggesting that the ringedphocids species that is similar in size to the harbor seal, may also use a maternal foraging strategy.T-4-24:T-733It can be inferred from the passage that the females of[ZXM4]all phocids species differ from the females of all otariid species in that the female phocidsA.have shorter lactation periodsB.consume more food during lactationC.consume a higher proportion of fat storesD.forage for food occasionally during their lactation periodsE.deplete a smaller percentage of their fat stores during their lactation periods-------------------------------------------------------------------T-4-25:T-7-34The primary purpose of the passage is to[ZXM5]A.present evidence that several phocids species use the maternal fasting strategyB.explain why the maternal strategy typically used by phocids is different from the maternal strategy used by otariidsC.argue that zoologists’ current understanding of harbor seals’ maternal strategy is incorrectD.describe an unexpected behavior observed in harbor seals and propose an explanation that may account for the behaviorE.describe evidence concerning the maternal strategy of the harbor seal and suggest that the harbor seal belongs to the otariidrather than to the phocids family-----------------------------------------------------------------T-4-26:T-7-35According to the passage, until recently zoologists[ZXM6]believed which of the following about all phocids mothers?A.Their fasting periods after giving birth were typically shorter than those of otariids.B.Their lactation periods were generally as long as those of comparably sized otariids.C.They acquired only moderate energy stores in the form of blubber before arriving at breeding sites.D.They depleted less than a third of their stored body fat during lactation.E.The replenished their fat stores only after their lactation period ended.-------------------------------------------------------------------T-4-27-T-7-36The author of the passage mentions ringed seals most probably in order toA.provide an example of a phocid species that fasts[ZXM7]throughout its entire lactation periodB.provide an example of a phocid species whose maternal strategy is typical of phocid speciesC.provide an example of a phocid species that may deplete an even higher proportion of its fat stores during lactation than harborseals doD.support the assertion that harbor seals are smaller than many other phocidsE.support the assertion that harbor seals’ maternal strategy may be related to their small size[ZXM1]Q 24：[ZXM2]Q 26：[ZXM3]Q27,解答该问题，关键要找个论据的观点，这个观点就是⽂章的第⼀句话；的不⼀样；作者通过by contrast来进⾏对⽐，⽤⼀个fasting strategy，因此是时间快慢问题；因此只[ZXM5]D项最不具体，最虚；[ZXM6]GWD录⾳：细节题做；⼀定要找到phocids mothers如果选项都有only的时候，不要因为only就⼲掉E：C强调的获得能量的形式，E强调的是获得能量的时间；原⽂读到的是能量获得的时间；题⽬问的作者提到这个东西是为了什么，问作者的⽬的，因此应该找作者的观点，⽽作者的观点应该是在后⾯；。

鉴定wgd的方法 -回复

鉴定wgd的方法-回复“鉴定wgd的方法”在现代科技发展的时代，电子设备的普及使得网络犯罪、虚假信息泛滥成灾，对于信息的真实性的鉴定成为了一个迫切需要解决的问题。

其中，鉴定wgd（Wrongful Generation of Data）的方法，也就是检测数据的误生成，对于维护信息的可靠性和保护用户权益具有重要意义。

本文将详细介绍一种1500-2000字的文章，以回答“鉴定wgd的方法”。

第一步：收集原始数据鉴定wgd的第一步是收集原始数据，也就是获得需要鉴定的待检测数据。

这些数据可以来自不同的渠道，例如网络、传感器、数据库等等。

确保原始数据的完整性和真实性是鉴定wgd的前提。

第二步：数据清洗与预处理在进行wgd的鉴定之前，需要对原始数据进行清洗和预处理。

这个过程包括去除数据中的噪声、异常值和缺失值，同时进行数据的归一化和标准化。

此外，还可以进行特征提取和降维等操作，以便更好地表示和分析数据。

第三步：选择合适的鉴定算法选择合适的鉴定算法是鉴定wgd的关键一步。

目前，常用的鉴定算法包括机器学习方法、统计方法和数据挖掘方法等。

其中，机器学习方法如支持向量机（SVM）、随机森林（Random Forest）和神经网络等，统计方法如假设检验和回归分析等，数据挖掘方法如关联规则挖掘和聚类分析等。

根据具体情况选择合适的算法，以提高鉴定wgd的准确性和效率。

第四步：构建鉴定模型在完成算法的选择后，需要构建鉴定wgd的模型。

模型的构建包括特征选择、训练集与测试集的划分、模型训练和模型优化等步骤。

特征选择是选择对wgd鉴定有重要贡献的特征，可以使用特征选择算法如相关性分析和信息增益等。

训练集与测试集的划分是为了评估模型的性能和泛化能力。

模型训练是使用已知标签的数据对模型进行训练和参数估计。

模型优化是通过调整模型的参数和超参数以提高模型的性能。

第五步：模型评估与验证模型的性能评估是鉴定wgd的重要环节。

常用的评估指标包括准确率、召回率、精确率、F1值和ROC曲线等。
