If the slot is to remain empty, install a switching-module filler plate.
Blank faceplates and cover panels serve three important functions: they
prevent exposure to hazardous voltages and currents inside the chassis; they
contain electromagnetic interference (EMI) that might disrupt other equipment;
and they direct the flow of cooling air through the chassis. Do not operate the
system unless all cards, faceplates, front covers, and rear covers are in place.
Statement 1029
All Catalyst 4900M series supervisor engine modules and switching modules are
installed in horizontal chassis slots that are numbered from top to bottom.
Invisible laser radiation may be emitted from disconnected fibers or
connectors. Do not stare into beams or view directly with optical instruments.
Statement 1051
Voltages that present a shock hazard may exist on Power over Ethernet (PoE)
circuits if interconnections are made using uninsulated exposed metal
contacts, conductors, or terminals. Avoid using such interconnection methods,
unless the exposed metal parts are located within a restricted access location
and users and service people who are authorized within the restricted access
location are made aware of the hazard. A restricted access area can be
accessed only through the use of a special tool, lock and key or other means of
security. Statement 1072
To prevent ESD damage, handle switching modules by the carrier edges only.
