Catalyst 4507R+E Clock Module

[aron.bernasconi]

Hi,

I noticed that my 4507R+E chassis have the following module installed:

WS-X4K-CLOCK-E

I found in this EOL announcement that it's the clock module for 4507R-E chassis and is EoS since 2013:

Why the same module is installed in the new chassis and there are no spare parts available ?

Thanks,

Aron
