HP swicth 2524: J4131B and J4853A

Dear Sir/Madam,
I used two switch HP 2524 connect together by fiber cable with J4131B module on each site.
Recently, 1 of both J4131B wrong so I use J4853A for temporary but "they don't run"
Help me please !
Thanks a lot

Are you now using two J4853A's? You need to match the transceiver types when using fiber.

Also you must reboot the switch when changing transceiver types.
