POE Blade on 4506 switch

[Kevin Melton]

Forum

Some time ago, a Customer of mine purchased the following blade and installed it in their 4506 switch.

NAME: "Linecard(slot 4)", DESCR: "10/100/1000BaseT (RJ45)V with 48 10/100/1000 baseT voice power ports (Cisco/IEEE)"

PID: WS-X4548-GB-RJ45V , VID: V08  , SN: JAE1127P4XW

I knew that this was a POE blade, but when we plugged a POE device into one of the ports on that blade, it did not supply power.

I am trying to figure out what we are missing to make this blade provide power...

Thank You

  Look at the code level and also the power supply. If it's an old 4506 non E chassis and it only has 1300 watt power supplies it will not power  up the ethernet ports , you would have to order higher power supplies.

Post the output to the command "sh power inline".

Can you ensure the interface configuration does not have a "power inline never"?

[Kevin Melton]

Sure Leo  Here is teh output:

I am not sure but I do know I have not issued that command "power inline never" on the switch, and I am the only administrator for the switch...

[Leo Laohoo]

The command "power inline never" is not used because the "Admin" column is "auto".  Had the command been used, the output would've been "off".

I knew that this was a POE blade, but when we plugged a POE device into one of the ports on that blade, it did not supply power.

There's probably a cable problem.  Run the following command, in order:

1.  Command:  test cable tdr interface ;

2.  For a 4500 chassis, you need to WAIT for approximately 61 seconds;

3.  Command:  sh cable tdr interface ; and

4.  Post the output to #3.

Here is the output as requested.  I waited the recommended time for the output:

HI,

It looks the module issue. I bleieve you have already checked the power supply units on the device and tried reseating the card. If yes then go ahead and RMA the module.

Regards

Inayath

[Kevin Melton]

Actually I have not checked the power supplies on the unit or reseated the Card. 

Here is the output from a "sho module" command which shows the two power supplies installed in the unit...

NAME: "Power Supply 1", DESCR: "Power Supply ( AC 1000W )"
PID: PWR-C45-1000AC    , VID: V04  , SN: AZS102411TA

NAME: "Power Supply 2", DESCR: "Power Supply ( AC 1000W )"
PID: PWR-C45-1000AC    , VID: V04  , SN: AZS102411ST

Should these be lighting the module?  Or do we have the incorrect power supplies to light the module?

If these are the correct power supplies, then the next step for us based on your answer would be to perform a reseat of the card.  Can this be done hot swap style, or is this a power down the whole switch scenario?

[InayathUlla Sharieff]

Show module  >> Will give you the module status

Show diag result module X  detail >> This will give the details of the module statistics or information.

show environment status >> This will give you the PSU status wheather they are good or bad.

2- Yes the modules are Hot Swappable hence you dont need to perform complete shutdown of switch.

All indications at this point indicate that the module is good.  Once again, are the power supplies providing enough wattage to power the module and enable it to provide POE?  I am concerned that perhaps these power supplies are not strong enough.

Please read my previous reply , 1000 watt power supplies will not power up the poe power inline function  , you must have higher wattage power supplies of at least 1300 watts.
