Facing issue with POE for WS-X4648-RJ45V+E module on 4500

[vinod.mali]

                 Hi guys,

My peo module  WS-X4648-RJ45V+E i on 4506 is getting faulty i.e  the desktops are getting connected but the module is not able to deliver power to the ip phone.

I tried and replaced the module  but it worked for  some time and again got faulty.This way my three modules have gone faulty even I tried and changed the slot but no results.

I am not able to trace out whether this issue is with some phones connected on the moudle.

thing is the show power commands o/p seems to be normal, once the power over limit logs are getting generated prior to the failure of POe on the module.

[p.mcgowan]

how many power devices have you connected to the line card?

what type of phones are you trying to connect?

the WS-X4648-RJ45V+E supports up to 30W of inline power per port on up to 24 ports simultaniously.

Can you post the errors which are generated in the logs?

[Mandlenkosi Nkiwane]

I have the exact same issue and Cisco Tac has not been able to identify the issue. I am going to replace my second module in the space of 2 weeks.

My issue has been that some ports are ok and some just stop delivering power on the module. I found out that the line card is divided into 6 ASICS with 8 ports each. On the previous module I had issues with 16 ports (Fa3/32 - 48) pointing to the last two ASICS being bad. On the current module I have an issue on 8 ports (Fa3/16 - 23). Looking at the module it does not show any signs of any issue. Show tech does not indicate any issues either, all I see are phones rebooting and the interface showing 0v for inline power.

My next step is to move this module to a different slot and see if the problem follows....

[Leo Laohoo]

Try this:

1.  Command:  test cable tdr interface ;

2.  Wait for approximately 61 seconds (takes longer on the line cards of the 4500/6500 as compared to the supervisor card);

3.  Command:  sh cable tdr interface ; and

4.  Post the output.

Just checking if someone else has been facing this issue very frequently on C4507R-E / 12.2(54)SG1 / X4648-RJ45V-E

Oct 31 00:42:59.573 UAE: %C4K_IOSMODPORTMAN-4-INLINEPOWEROVERWARNING: Module 6 inline power exceeds threshold: status changed to 'Pwr Over'

After which the ports go down and line card reseat/reset fixes the problem.

We had checked with TAC, as per the engineer this suspects to a problem on the PoE daughter card on the line card, suggesting a replacement, but we had replaced almost 2 different line cards. This issue is still appearing on different switches.

Almost about 40 avaya Ip phones are connected on the module.

folowing errors are generated for the module

INLINEPOWEROVERWARNING: Module 2 inline power exceeds threshold: status changed to 'Pwr Over'

INLINEPOWEROK: Module 2 inline power within limits: status changed to 'Ok'

This problem could eb related to a known bug, are you also using 1400W power supplies?

1

%C4K_IOSMODPORTMAN-4-INLINEPOWEROVERWARNING:

Inline power exceeds threshold:Module status changed to 'Pwr Over'

This message indicates that the measured PoE is higher than the  configured value. The switch has either misconfigured PoE or an  unauthorized powered device that is connected to the switch and is drawing a  lot of PoE. In installations with a 1400 W DC power supply, this warning can  be a false positive.

Recommended Action:

You can use the show power detail command and  keyword or the show module command to compare the adminstrative  (configured) power (measured) consumption to the operating power  consumption. Verify that PoE is set correctly and that no unauthorized  powered devices are connected to the switch. For more information, refer to  bug ID CSCef49715.

bugID - CSCef49715;

Symptom

:

Catalyst 4500 with 1400 DC power supply may report "Pwr Over" or "Pwr Fault"

status for the following modules

- WS-X4248-RJ45V

- WS-X4248-RJ21V

- WS-X4548-GB-RJ45V

The following logging messages may also be generated

%C4K_IOSMODPORTMAN-4-INLINEPOWEROVERWARNING: Measured inline power higher than

configured value

%C4K_IOSMODPORTMAN-2-INLINEPOWEROVERCRITICAL: Measured inline power exceeds

module limit

Condition:

The above symptoms are typically generated if one of the PoE devices connected

to the module is drawing more power than it should. Make sure the connected

devices are not drawing more power than expected. However, in systems using

1400W DC power supplies, it is also possible that due to an anomaly in the

measuring mechanism in these linecards, the messages and associated status are

erroneously displayed. There is NO functionality/performance impact due to this

condition. The modules are safe and would have no impact to the operation of the

switch or the connected PoE devices.

Troubleshooting steps:

This situation may be caused by a device that is using more inline power than

allocated. Please make sure that the right amount of inline power has been

allocated to each device. If the inline power allocation is correct, start

pulling out one device at a time and see if the power usage decreases as

expected. (You can use the command, "#show power detail" to see the inline

power allocated to the module (admin) and the inline power used (operating).)

If the "inline power used" decreases sharply when a device is disconnected,

chances are that this device is using more inline power than allocated.

Avoiding using this device should solve your problem.

If after disconnecting all the devices on the module, the inline power usage

is still high, and the system does not use 1400W DC power, call TAC.

Workaround

:

On 1400W DC powered systems, this is a cosmetic problem but here are the

workarounds

- If this happens with PWR-C45-1400DC-P (DC power supply), using

other type of power supplies (e.g. AC power supply) would avoid this problem

- To prevent this from happening with this combination of Power Supply and

Linecards, make sure to insert the modules atleast after about 1 second after

the 12v (data) and 48v (inline power) power supply switches has been turned

on. In other words, power cycle the switch without these linecards in the

chassis and insert them once the switch is powered up.

If this message is seen on a system with 1400W DC power, please refer to the

steps mentioned in "Recommended Action".

Recommended action:

1. Collect the output of "show power detail".

2. Contact TAC to open case and attach the above output.

3. In agreement with TAC, please raise an RMA from Mfg-new and EFA the board.

Please rate the post if helpful

I have gone through this bug, unfortunately the switch is not using the 1400 w ppwer supply.

[Leo Laohoo]

Have you tried the TDR?

[vinod.mali]

the tdr testing is planned in weekend will update you with the o/ps

[Akhtar Samo]

We have been also hit by this problem. The switch(C4507R-E / 12.2(54)SG1) is having 4200ACV PS so the bug CSCef49715 doesn't apply to our case also.

We observed that all the ports on module-1(X4648-RJ45V-E) had 0W (Power from PS and Power to device), all desktops were fine only phones were affected.

We had tried hw-module reset to recover from this problem.

Just wondering if any one has found out a root cause for this problem ?

Hi vinod,

I 'm having the same problem with 4506E switch with cat4500e-entservicesk9-mz.122-54.SG.bin, and line cards

WS-X4648-RJ45V+E.

something weird because the ports that have problems are in card # 3, and the number of ip phones is  low

Did you clear this issue??

Hi,

I am facing similar kind of issue with 4510R+E switch.Model is  WS-C4510R+E.

Is there any fix for this.Power seems normal to the switch as well

Hi Vinit,

In my case I clear this issue after applying the command ( for the module with problem)

hw-module module 3 reset 

regards

[Mandlenkosi Nkiwane]

I would do a hardware reset , reseat and if both don't work...engage Cisco TAC and get it replaced.
