Raising Tray for Access to PEMs

You should raise the tray only when necessary to access the Power Entry Modules (PEMs), typically for replacement or to install a second PEM. Figure 12-4 shows the tray in the raised position.

To raise the tray to provide access to the PEMs, use the following procedure:

Step 1 Remove the securing screws as necessary.

Step 2 With two hands, pull the tray towards yourself and up.

Step 3 Raise the tray to the upper position and lower it onto the upper slots.

Step 1 Remove the bracket from the kit.

Step 2 Place the bracket in position as shown.

Step 3 Screw in and tighten the captive screw.

Step 4 Insert one end of the cable tie through the hole in the bracket.
