2 Hardware Installation
CommPlete Communications Server 13
is the PC that runs the MultiModemManager software or, optionally, a third-party SNMP manager. Note
that for 10M bps connection, you can use Category 3 (Cat 3) or Cat 5 cable; for 100M bps connection you
must use Category 5 (Cat 5) cable.
Serial Cabling
Use the 9-pin RS-232 connector on the back of the CC9600 chassis for diagnostics and configuration.
Network Connections
If any port on the MR9600-100 is set for full duplex operation, the device (or LAN) connected to that port
must also be set for full duplex operation. Refer to the following sections on 10M bps and 100M bps ports
for specific requirements.
10M bps Ports
The five 10M bps ports are used internally for the four CommPlete segments and the Controller. The 10M
bps ports operate at a user-selectable effective speed of 10M bps in half-duplex mode, or at 20M bps in
full-duplex mode. In either mode, the twisted-pair connector can operate over 100 meters of Category 3, 4,
or 5 UTP/STP cable. Note that the MR9600-100 back panel has two RJ-45 connectors. Refer to Figure 2 for
the proper connector type (cross-over or straight through).
100M bps Ports
The two 100M bps ports use standard RJ45 twisted-pair connectors with unshielded or shielded twisted-
pair (UTP/STP) wiring. The 100M bps ports operate at an auto-negotiable neffective speed of 100M bps
(in half-duplex mode) or 200M bps (in full-duplex mode). In either mode, the twisted-pair connector can
operate over 100 meters of Category 5 UTP/STP cable. (Cat 3 cable can be used if the 100M bps port is
running at 10M bps.)
The two 100M bps ports can auto-negotiate for 10/20/100/200M bps operation. Note that the MR9600-100
back panel has two RJ-45 connectors. Refer to Figure 2 for the proper connector type (cross-over or
straight through).

Cable Types
Under most conditions, the ports on the MR9600-100 may use normal straight-through cables. Some
circumstances, however, may require cross-over cables (i.e., cables in which the twisted-pair outputs have
been crossed). See Appendix B for more information on cable pinouts.
