Power Supply Installation Guide

DC power supply installation

This chapter provides instructions to install the DC power supply in the

Ethernet Routing Switch 8300 chassis.

See Nortel Ethernet Routing Switch 8300 Administration, NN46200-604 for

the minimum Ethernet Routing Switch 8300 software version required to

support the hardware.

ATTENTION

Nortel recommends that you install each power supply on its own dedicated

branch circuit to ensure that a fault on another branch circuit does not cascade

to other branch circuits.

Prerequisites

•

Verify that you have the following tools and materials:

— cable

—

crimping tool for crimping the lugs onto the cable

—

heat gun to shrink the tubing around the cable (optional)

—

7/16-inch hex wrench

—

Phillips screwdriver

•

Determine the minimum number of DC power supplies to be installed.

For more information, see “Determining the minimum number of DC

power supplies” (page 28)
