asw-b-eqiad is no more part of the prod infra and has been removed from monitoring.
Not sure if all the DCops steps are here but the gist is:
Mentioned in SAL (#wikimedia-operations) [2018-11-06T13:10:14Z] <XioNoX> zeroize asw-b-eqiad (decom) - T208788
It looks like those switches are too old for the request system zeroize (Command introduced in Junos OS Release 11.2 for EX Series switches.)

The command exists but doesn't seem to do anything other than rebooting the stack.
@Cmjohnson, could you try the front LCD panel method from the following?

As a precautionary step, I set the root password to a dummy non prod one, removed the SNMP community, ensured no other passwords were on the device and did a file delete purge of all the previous configurations, on both master and backup nodes.
