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.

If A1 is configured as a link, it blinks on power-up with no established link. (The default setting is for A1 to be
configured as a link.)

System can still operate with CMOS failure. All configuration data has been lost in the affected CMOS section,
and default values have been supplied.
3
System can still operate with a low battery. Configuration data may be lost if the Multiserver loses power.
