Introduction
This chapter contains only general information about installing the CC9648 chassis. The equipment should
be installed only by a qualified service person.
The CC9648 is designed to be installed in a standard 19-inch-wide rack cabinet. Figure 1 shows a fully
loaded chassis with one controller card, two power supplies, and a full complement of RASCards and
modem cards.

Pre-Installation Notes
• Unpack hardware carefully.
• Perform a visual inspection of the hardware. If you are concerned about the condition of the chassis,
call Technical Support.
• All installation must be done by a qualified service person.
• Consult the manuals for your other components (PS9648, MR9600, MTRAS96, and MTxxxxHD8)
before they are installed into the CC9648.
• To reduce emissions, be sure to use blanking plates to cover empty slots in the CC9648 chassis.
• Only connect like circuits. In other words, connect SELV (Safety Extra Low Voltage) circuits to SELV
circuits and TN (Telecommunications Network) circuits to TN circuits.
WARNING: Interconnection directly, or by way of other apparatus, of ports marked “SAFETY WARNING
see instructions for use” with ports marked or not so marked may produce hazardous conditions on the
network. Advice should be obtained from a competent engineer before such a connection is made.

The chassis can work with
one or two PS9648 power
supplies. The second power
supply is redundant. If any
of the outputs on either
supply is low or fails, the
other supply takes over with
no switchover period,
producing all the power
required to run the system.
(Both power supplies must
be turned on; when both
supplies are operating, they
share the load.)
The controller module
contains a processor and
memory for intelligent
operation of the rack, plus
an integrated Ethernet
concentrator.
