Installation Guidelines

Replacement Installation Guidelines

If the PRE3 is replaced in a redundant system containing two PRE3s, the standby (or newly installed)

PRE3 automatically assumes the configuration of the active PRE3; do not configure the new PRE3.

Required Tools and Equipment

You need the following tools and equipment to install the PRE3:

• A 3/16-inch flat-blade screwdriver

• An ESD-preventive wrist or ankle strap with connection cord

• A terminal console to connect to the PRE3 after it is installed

Powering Off the System

If you are installing or replacing a single PRE3, power down the system using the following procedure:

Caution If you have redundant Power Entry Modules (PEMs), set both power switches to the off (0) position. See

Figure 3 for the DC PEM power switch and Figure 4 for the AC PEM power switch.

Step 1 Attach an antistatic strap to your wrist or ankle and to an ESD socket on the chassis, or to a bare metal

surface on the chassis or frame.

Step 2 Set the power switch to the off (0) position.

Step 3 Go to the Installing or Replacing a PRE3, page 11.
