Connect and Route the External Timing and Power Cables
Perform the following steps to connect and route the external timing and power cables at the rear of the
chassis:
1. Optional. Connect and route the external timing cables; see Figure 4-29:
Attach the DB-9 ends of the external timing cables to the primary and secondary connectors, labeled
“PRIMARY” and “SECONDARY”, at the center rear of the SmartEdge 1200 chassis; tie the cables to
the rack.
If your cables do not have a connector on the system end, you can install an adapter, available as an
option, in each chassis connector and then wirewrap the cable pins to the adapter.
2. Tie and route the chassis ground cables and the power cables to convenient locations on the rack.
Note The SmartEdge OS does not support the alarm, status, and RS-232 dial-up modem ports.
