Replace asw2-d-eqiad VC cable
Closed, ResolvedPublic

Description

This one is slightly more tricky than T268804.

https://netbox.wikimedia.org/dcim/cables/3406/

The logs are filled with:

Nov 26 07:32:53 asw2-d-eqiad fpc8 Rear QSFP+ PIC Chan# 2: Rx power high warning cleared
Nov 26 07:33:53 asw2-d-eqiad fpc8 Rear QSFP+ PIC Chan# 2: Rx power high warning set

But it's not possible to know which QSFP they're talking about.

As the Netbox import revealed that both sides of that DAC report a miss-match in length, it likely that it's the faulty link.

As it's carrying live traffic, please sync up with me before replacing it.
