SFP Module won't work.

[TheGandalf]

Hello.
I recently bought a WDM 1310/1550 nm SFP module.
It does not work as I want it to.

I can see the console log that I get this message: "Ports: port 26 XCVR change type. Check the switch configuration"

I can see this message refers to # 408; http://whp-hou9.cold.extweb.hp.com/pub/networking/software/3500-5400-6200-ELRG-0207-K_12_XX-Book.pdf

Which says: " 408 Port xcvr type change. Check switch config info The transceiver has been changed in the specified port. Check the switch configuration. RMON_PPMGR_XCVR_HOTSWAP_TYPECHG

Is there anyone out there who can help me? :)

What Switch (Model)?

What Switch Module (for SFP+ I suppose) is used (Model)?

What Switch's Software version?

What Transceiver (Model)?

Is the Transceiver a HP/HPE genuine part?

What does the statement "It does not work as I want it to." mean?

Is the Transceiver (SFP+ I suppose) recognized or not? if so (if recognized) what issue are you experiencing?

Try the "show tech transceivers" command and check if the transceiver is recognized by the switch. Output should be something like this:

PROCURVE# show tech transceivers

transceivers

Transceiver Technical Information:
 Port # | Type      | Prod #      | Serial #            | Part #
 -------+-----------+------------+------------------+----------
 26     | SFP+SR    |     J9150A | CN2BDRN2S3  | 1990-4065

 - Shutdown the port then bring it up again

 - Reboot the switch

 - Get the vendor to code the SFP with a proper Procurve part number

You haven't provided much information about the SFP, but Procurve-branded WDM SFPs are virtually non-existent (some were made in Germany at one stage, 10 years ago) so it's likely non-Procurve.
You haven't told us what switch you have, but the link you refer to is for 3500/5400 switches. These switches are particularly good at detecting non-Procurve SFPs and locking them out. Your vendor should have coded the SFP properly for you.
