Anyone encounter any issues when uplinking a Ruckus 7982 to a PoE enabled 5406zl Copper module. There is plenty of power availabe but all I get in the logs is the following:

I 09/06/08 22:12:17 00565 ports: port A11 PD Removed.
I 09/06/08 22:12:03 00561 ports: port A11 Applying Power to PD.

I 09/06/08 22:12:00 00565 ports: port A11 PD Removed.

Hi Brandon,

Is the AP failing to power up? I am not from electrical background but here is what I found. It may be due to switch rack's power circuit and the metal racks for the AP sharing the same electrical grounding.This can cause the full ground loop between switch and the AP and cause AP to fail.

I am not sure if this is the exact reason and if you have the above mentioned combination. I suggest opening a case with Ruckus TAC for this as this is not something common.

I am having this exact same issue with all of my POE switches. Only solution I found was to add external power to the AP for about 5 seconds and then remove and the devices would stay powered. Not the perfect solution but worked for what I needed today. I am looking to see if anyone has a fix for this.

@Rahul,

The APs are not powering up, that is the issue. I am using POE enabled switches to power these devices. Not external power.

@Hensley

Thank you for the information. I shall test this as well. It seems to only be on the 5406 module. I can power them on a 3500yl, 2910, 2620 and 2610 with no issues. I wonder if its a FW bug on the 5406 module.

Quick question though, are you using a POE injector and then switching the cable over to the switch or are you leaving the cable plugged in on the POE port with POE enabled on the switch port and then using an external power supply? Only reason I ask is the difficulty in getting an external power supply to an AP in the ceiling.

I have a 2910, 2610 and 5406 switch that I tried with all of these and still have the same issue.

I have not mounted in the ceiling as yet due to this issue so I just have them where I can access AC power until I can figure if it's a switch firmware issue or issue with the AP's.

I am not using a injector just a standard AC adapter that I found that fits.

If you have HP switches that these devices work on can you share what firware you are using on both switches and AP's please?

Please go ahead and open a support case so that we can get to the bottom of the underlying issue. You shouldn't settle for a workaround as a power-failure would put you back in a power-down situation.

I'm experiencing the same issue with a 5412zl series switch. Tried a PoE injector as a work around to eliminate switch firmware issues and still no joy.

All,

Just an update, after leaving the APs connected to the switch, it finally powers them up after 4 minutes. Not sure how long you have attempted to leave them on there. Some 7982's power right up, and some don't. Grabbing serial information of the ones that took 4 minutes.

I have had good success with HP Procurve devices that are rated PoE+

For example the HP 3800 and 2920 and the ZF7982.

No issues with our HP 5406zl or 2920 switches..

Seeing the same thing on an HP 2530-24G PoE+ switch. In addition we get the PoE light blinking orange, which is supposed to indicate a warning condition (but not a fault condition.) Switch thinks it's delivering power even though the light is on, but AP is not powering up.

Never mind, firmware upgrade on the 2530 resolved the issue, despite no mention of PoE in the release notes. If anyone is having this issue, probably worth making sure you're up to date.

EDIT: Now on firmware YA.15.12.010

I had a similar issue with an HP switch (2910-24G-PoE+ al) and 7982's. I would get the orange blinking PoE light on an HP switch, tested with W_15_08_0012 and W_15_12_0011. With the firmware downgraded to W_14_38, the AP's powered up, but I didn't want to revert the firmware. Also, tested on a CIsco PoE switch, the AP's would not power.

I RMA'ed one of the 7982's and it worked on both the Cisco and updated HP. The rest of the AP's (being used with Ruckus PoE injectors) are currently being RMA'ed. The existing "broken" AP's had serial numbers starting with 3213 and 3313, while the new AP started with a 36. This lends credence to another forum posting about a change in hardware for the later revisions of the 7982's. If you are having a similar issue, please try RMA'ing at least one AP to test, even though you may not think it will fix the issue.

Hey guys just wanted to let you know that I had the same problem that you guys have. I was using an e5412 chassis switch and for the life of me couldn't get them to turn on. I figured out that if you go into the poe settings of the HP and turn off Dot3 LLDP TLV your ap will turn on with no problem at all. You have to do this for every port but it worked no problem.
