DC/DC Converter Units and Air Dividers (J7000 Only)

The J7000 workstation has two DC/DC converter units and two air dividers on its left side.
(The J5000 does not require any DC/DC converter units nor the air dividers.) The DC/DC
converter units and air dividers are attached to the J7000 by metal tie-down straps. Each
DC/DC converter unit connects to the system board by a 30-pin connector.
Removing the DC/DC Converter Units and Air Dividers
To remove the DC/DC converter units and air dividers, do the following:
1. Remove the J7000 workstation's top panel and left side panel.
2. On the left side of the workstation, remove the four T-15 Torx screws from the front air
divider, and then remove the front air divider.
3. You will see two tie-down straps that are wedged into place over the DC/DC converter
units and the rear air divider. One edge of each metal tie-down slips into a slot on the
system board fan wall, and the other edge is secured by a T-15 Torx screw on the rear
panel of the workstation. Each metal tie-down is also secured to the rear air divider by
a T-15 Torx screw.
To remove the tie-downs:
a. Remove the T-15 Torx screws securing the tie-downs to the rear air divider.

wall.

board. The 30-pin connector will release from the system board.
