Connect Intershelf Power and Grounding Cables
After obtaining approval from a supervisor, an authorized power installer should follow these steps to
connect the intershelf power and grounding cables to the individual machines in the Cisco BTS 10200
Softswitch. The intershelf power cables are provided with your shipment.
Caution Ensure redundancy of power feeds to your system, so that a single point of failure does not cause a loss
of traffic:
— For DC systems, power each host from two separate (redundant) DC power feeds.
— For AC systems, power Side A hosts from a separate power source than Side B.
Step 1 For DC-powered systems, connect the cables as follows:
a. Use the specific DC power cable that was provided for each machine in your shipment.
b. Connect the intershelf DC power cables from the power distribution unit (PDU) to each of the
devices in the rack. There are two intershelf DC power cables per machine (one for power feed A
and one for B). See Table 1 on page 18 for the complete cabling list.
c. Following local electrical codes, connect the ground cables from each of the devices in the rack to
the PDU grounding point (either of the two grounding screws on the PDU rear panel). See Table 1
for the complete cabling list.
Step 2 For AC-powered systems, connect the cables as follows:
a. Use the specific AC power cable that was provided for each machine in your shipment.
b. For each A Side machine (A Side EMS, CA, and Ethernet Switch) connect the intershelf AC power
cable from the device to one of the AC power strips.
c. For each A Side machine (A Side EMS, CA, and Ethernet Switch) connect the intershelf AC power
cable from the device to the other AC power strip.
d. Connect the intershelf AC power cable from the Alarm Panel to either of the power strips.
