Connecting and Routing the Cables

SmartEdge 1200 Router Hardware Guide
Connect the Cables from the Rear of the Chassis
Perform the following steps to connect the cables from the rear of the chassis:
1. If you have installed external timing cables, attach the unterminated ends of the cables to the wire-wrap
posts of the external equipment. For the external timing cable specification, see the “External Timing
Cables” section on page A-3 in Appendix A, “Cables and Pin Assignments.”
2. Complete the power connections to the external fuse panel or circuit breaker panel. The procedure for
the circuit breaker panel is beyond the scope of this book; to complete the connections to a fuse panel,
perform the following steps:
a. Remove the fuses for the connectors on the external fuse panel that you intend to use for the four
pairs of power cables.
b. Connect the primary power zone 1 cables (A1) to their –48V and RTN connectors on the external
fuse panel.
c. Connect the primary power zone 2 cables (A2) to their –48V and RTN connectors on the external
fuse panel.
d. If you are installing redundant power, connect the backup power zone 1 and power zone 2 cables
(B1 and B2) to their –48V and RTN connectors on the external fuse panel.
You are now ready to power on the system and check the operating status; continue with Chapter 5,
“Determining Operating Status.”
Warning
Risk of electrical shock. After the power cables are connected to the chassis and the fuse
panel, the system is fully powered on; there is no power switch. To reduce the risk, always
remove the fuses from the fuse panel or if there is a circuit breaker, switch the circuit breaker
to the OFF position, before connecting or disconnecting a power cable.
