ICX7450 and broken PoE when HP Color LaserJet CP3505 or HP Color LaserJet 3800DN in connected to the switch

Hi

 

Did anybody noticed problems with PoE in ICX7450-24P and ICX7450-48P switches ?

We have very odd issue that if we connect HP Color LaserJet CP3505 or HP Color LaserJet 3800DN to ICX then PoE stops working and we see "PD Overload" errors in syslog. Problem exist even we connect HP Printer to 'disabled' port.

 

We opened cased with TAC, they RMA two switches. But after replacement nothing change, we also tested couple of other 7450 having always same problem.

 

Looks for other people having similar problems.

I think your printers need less power the you give them. (Default behaviour is class 3 which is 15400)

You should try to limit power of PoE port before plugging cable or power down it to class 2

 

 

Just pick up one:

 

 

Switch(config)#inline power ethernet 1/1/1 power-by-class 2

or

 

Switch(config)#inline power ethernet 1/1/1 power-limit 7000

Also share the output of "show inline power" command please.

Are you seeing this issue on both the 24P and 48P switches? On just one type?

These printers are powered from wall, not PoE. 

 

What is happen - PoE stops working on all switch ports if we connect  HP Color LaserJet CP3505 or HP Color LaserJet 3800DN to ICX7450.

 

Eg.

We have PoE (inline power) configured on ports 1/1/47 and 1/1/48. We connecting Aruba APs to ports 1/1/47 - 48. Everythings works fine. We connecting HP CP3505 to 1/1/1 and what happen next:

 

PoE: Power disabled on port 1/1/47 because of PD overload.
PoE: Power disabled on port 1/1/48 because of PD overload.

 

On 1/1/1 we don't have PoE enabled.

Even same happen if we disabled 1/1/1 by command 'disable'

Limiting PoE amount on port or setting PoE class to 1,2,3 or 4 didn't helped of course.

Jerry, This is a known issue on the -48P you should open a TAC case and request an RMA for your swicthes. If they are in any doubt please ask them to conatct me directly.

They already did RMA which not helped with solving problem

could you write few more word as It's known problem about it ? Any TSB ?

What code are you on? 8030 and the 7450's have been awful for POE related issues, we've had some luck with 8030f, which was partially written to resolve issues we were having with Avaya phones and Cisco AP's.

 

This isn't quite what you're experiencing, but was fixed in 8030f, please note if you are on the 8040 code train, NONE of these have been fixed to date, I would recommend 8030f.

 

I'll also note that we found that limiting the power output on ports 1-8 (the HPOE ports) is helpful if you don't have any actual HPOE devices.

 

On the code you are on, you may try moving the printer to a port that isn't 1-8 (HPOE Port)

 

conf t

interface 1 1/1/1 to 1/1/8

inline power power-limit 30000

 

Another (undocumented) function in 8030f is the new command to work around poorly functioning PD's

 

At a global level you can use as follows

 

inline power adjustment class (0-4) minumum (value)

 

We had to do this for a specific Avaya IP phone that would negotiate LLDP to 2600 watts, but then actually try to pull more than that. 8030 train changed the behavior of the POE circuit, in that if a device negotiated less power it would not ramp back up.

 

Finally, you can also look into the inline power non-pd-detection enable in 8030f, which is described here

Here are a few of the POE bugs and issues present that were fixed in 8030f (and remain bugs in 8040)

 

Defect ID:

DEFECT000574609

Technical Severity:

High

Probability:

High

Product:

Brocade FastIron OS

Technology Group:

Management

Reported In Release:

FI 08.0.30

Technology:

Configuration Fundamentals

Symptom:

Newly connected PDs do not power up.

Condition:

With PSE to PSE connected and PoE enabled, other PSE might get detected as PD and power gets injected. This could cause the newly connected PDs to not power up.

Workaround:

User need to identify which port is being injected power and disable power from that PSE to this port.

Recovery:

User need to identify which port is being injected power and disable power from that PSE to this port.
