Connect Power; Connecting The Ac Power Cord; Wiring The Dc Power Supply - Cisco Universal Access Server AS5300 Quick Start Manual

Connect Power

The access server is available with either an AC or DC power supply. You can also order a power supply as a spare if you decide
later that you need a different type of power supply or the power supply fails.
Warning Do not touch the power supply when the power cord is connected. For systems with a power switch, line
voltages are present within the power supply even when the power switch is off and the power cord is connected.
For systems without a power switch, line voltages are present within the power supply when the power cord is
connected.

Connecting the AC Power Cord

Take these steps:
Step 1 Connect one end of the power cord to the power connector on the rear panel of the access server.
Step 2 Connect the other end of the power cord to the power outlet.
Warning The plug-socket combination must be accessible at all times because it serves as the main disconnecting
device.

Wiring the DC Power Supply

If you ordered the access server with a DC power supply, follow the procedure in this section to wire the terminal block.
Warning A readily accessible two-poled disconnect device must be incorporated in the fixed wiring.
Warning Before performing any of the following procedures, ensure that power is removed from the DC circuit. To
ensure that all power is OFF, locate the circuit breaker on the panel board that services the DC circuit, switch the
circuit breaker to the OFF position, and tape the switch handle of the circuit breaker in the OFF position.
Note This product is intended for installation in restricted access areas and is approved for connection using 12 or
14 AWG copper conductors only. The installation must comply with all applicable codes.
Refer to the figure and follow these steps to wire the terminal block:
Step 1 Note the orientation of the DC power supply. The power supply cord should have three wires: +48 VDC, -48 VDC, and
a safety ground (green wire).
Note For central office installations, it is recommended to use a 6 AWG green ground wire with one end connected
to reliable earth. The other end of the wire should be crimped onto the double-hole lug provided in the installation
pack. The lug should be secured to the mating holes on either side of the chassis with the two screws included in the
accessory pack.
