There are five chassis positions available for
modules in the Multiserver 5000. These are
identified from bottom to top as module locations
A through E.

• The Communications Control Module (CCM) is

always in module location A.

• A space is reserved below the CCM for the

optional NMS module. Its module location
is “$.” Note that there is no “$” printed on the
rear-panel of the Multiserver 5000.

• Optional modules can fill module locations B

through E.
