求助!UniFi Switch 16 AT-150W 无法24Vpoe输出.

固件版本:4.3.13.11253 控制器版本:5.9.29.0 购入时间2017年11月.
控制器中只有POE+的开与关.并没有24V输出的选项.但是我看宣传页,包括用户手册都是写明了支持24V被动式POE输出的.那么问题出在哪里了呢?

看了一下宣传页是可以,控制器和交换机固件版本都升级了吗?你的设备端口设置没有这个选项吗?

固件升到4.3.13了,控制器倒是差几个版本,poe设置那里只有poe+和off的选项

截图出来上传啊……AC版本号也带上 :bangbang:

没法截图的话就自己先把AC升级到LTS或最新的版本:
LTS:5.6.42
当前最新版本「截止20Y0519」:Ver 5.12.66

从历史记录上来看3年前的某一个段时间的阶段里,AC上少数几个版本曾经讨论过撤销24V的输出,具体是否是AC版本引起的就看你自己升级对比一下了:

Updated Summary Concerning 24V Passive Support in UniFi Switch product line (8/25/17):

We will  **continue**  to provide hardware support for 24V Passive Power over Ethernet on all UniFi Switch models that previously featured 24V passive, including: 

- US-8-150W - US-16-150W - US-24-250W - US-24-500W - US-48-500W - US-48-750W

Any future switch models we will produce will not feature hardware support 24V Passive PoE. 

**Why we decided to take a different route:**  A few weeks ago, we [announced on the community](https://community.ui.com/questions/ec4940aa-b213-47fb-99c7-fd049af4f8f5) that due to the need to update our PoE mechanism and improve our switch function that we would be phasing out support for 24V Passive PoE. Since the initial post we heard from many of our community users who expressed dissatisfaction over this change and expressed they preferred a different course of action. A number of users expressed concerns about purchasing products, continuing 24V Passive support for already purchased devices, RMA complications that may arise, etc. 

At Ubiquiti, our customers’ feedback is of the utmost importance to us and we strive to listen and engage our customers to receive their input whenever we can. Accordingly, we heard and understood the concerns that were voiced to us we have decided to take an alternative course that we are confident will resolve many of the reported concerns. As a part of this announcement, we again reiterate the importance of our users upgrading their hardware as their UniFi deployments permit. 802.3af/at PoE+ offers many benefits over 24V passive including stability and convenience. Our Instant 802.3af Gigabit Adapters remain an alternative, affordable way to provide the benefits of 802.3af to older 24V Passive dependant hardware: https://www.ubnt.com/accessories/instant-8023af-adapters/

We want to express our thanks to all who weighed in and provided constructive feedback and to all of our community users for their continued participation.

我最开始描述里写了控制器版本:5.9.29.0
刚看你的回复我又尝试了5.12.66.
同样是POE设置那块只有"关闭"和"POE+"两个选项.
也就是说控制器和交换机固件都已经升级到最新的版本了.依旧没有24V输出的选项.

请把设备列表整个截图出来 :warning:我需要看到具体的设备型号
如果其他型号产品本身就可能不支持24V被动供电

补充说明:

由上述官方表述可明确的是仅US-8-150W - US-16-150W - US-24-250W - US-24-500W - US-48-500W - US-48-750W这几款固定型号的设备支持24V passive供电,其余型号并未设计该功能,所以如果LZ的交换机型号明确是US-16-AT-150W的话,该型号并未在上面的列表中存在,因此是可能不支持的。

另我找了一下自己客户群里对应正在运行的设备,证实US-16-PoE 150W是有支持24V passive的选项「客户未使用此功能」,截图见下,所以请LZ确认自己设备的型号:

我确认型号是US-16-AT-150W,那么就是这个型号的硬件本身就不支持24v输出了?

根本没查到你这个UniFi Switch 16 AT-150W型号的文档
「可能是早期的型号了,确实我真没见过这个型号……」,
但是这个UniFi Switch 16 AT-150W确实不在24V passive供电的支持列表里。

且当时的官方说法是:

Any future switch models we will produce will not feature hardware support 24V Passive PoE.

算是比较绝对的说法了。所以如果24V设备不多的找几个PoE供电模块接一下吧,UB的代理商一般都有这个规格的PoE供电模块的。市场上也有些劣质的18~24V的杂牌PoE供电模块,你也可以搜一下,虽然不建议用 :stuck_out_tongue:

:rofl:头大.当初是被卖家当成US-16-150W卖给我的.之前一直没用24v的设备,也就一直没注意到这回事.
说起来这型号固件应该也是和US-16-150W通刷的.

如果就一台交换机的话就考虑PoE供电模块吧,有几台的话看看其他几台是不是有不同型号的,这样互换就行了,这种产品应该没啥产量和销量的,不然我也不会没见过 :rofl:

恩,手上也有ubnt的24v供电模块,既然是硬件本身不支持也就只能上单独供电了,我一开始还以为是软硬件出了什么故障.也感谢你提供那么多有用的资料 :grimacing:
