Installing the Cisco AS5800
This chapter explains the proc edures for installing the acces s server. Installation involves the
following tasks:
1Connecting cables to the AC power supply (AC installs only)
1Rack-mounting the AC power supply (AC installs only)
2Rack-mounting the dial shelf
3Replacing the blower assembly, DC PEMs, and dial shelf card s or co ntroller cards
4Connecting power inputs to the DC PEMs
5Mounting the AC power safety cover (AC installs only)
6Rack-mounting the router shelf
7Connecting all remaining cable connections
Estimated time to install the access server hardware is between 2 and 3 hours.
Note If you are installing the optional AC-input power shelf, refer to the“Connecting to an AC
Power Source” section on page3-1.
This chapter assumes that you are installing the access server manually. If you have access to a
forklift or hydraulic equipment during the installation, you can omit certain steps, which are
specified later in this chapter.

Connecting to an AC Power Source

If your site has access to an AC po wer source only, you need to inst all the optional AC-input power
shelf (DS58-PWR-2AC) to convert to DC-input power for the dial shelf.
AC-input power is accepted using a separate, self-contained AC-input power shelf, which converts
AC-input power to DC-output for use by the DC-powered dial shelf. T he AC-input is supplied by
two AC power cables (CAB-DS-AC=, other options a vail able), con vert ed to –48V DC-output power
for the dial shelf PEMs using two AC-to-DC power cables (DS5800-CAB-A CDC=) supplied by
Cisco.
The AC-input power shelf is an optional component of the CiscoAS5800 and is used to convert
AC-input power into DC-output power for the DC-powered Cis co5814 dial shelf. The AC-input
power shelf contains two AC-input power supplies.
