Location: part 1, page 1, pane 3
Pane 3 provides instructions to prepare the installed appliance rack for the installation of additional compute nodes.
Always populate the compute rack units starting from the bottom most open slot, and work your way up.
Steps:
Remove the front and rear rack doors.
Unlock and open the front and rear doors.
Detach the grounding straps connected to the doors by pressing down on the tabs of the grounding strap’s quick-release connectors, and pull the straps from the frame.
Lift the doors up and off their hinges.
An image illustrates the location of the door hinges on the appliance rack. Four detail bubbles show a close-up of each hinge. A fifth detail bubble in the center shows how the grounding straps are disconnected from the frame.
Remove the filler panel(s) where the expansion node will be installed. The filler panels have snap-in attachments. No screwdriver is required to remove them.
Remove the cable tray that holds the pre-installed cables in place at the rear side of the rack.
Detach the pre-installed cables from the cable tray on the rack unit for the new expansion node.
Use a No. 2 Phillips screwdriver to remove the M6 screws from the cable tray.
Remove the cable tray from the rack. Save cable tray and screws for future use.
An image illustrates the way the cable tray is attached to the rear rack rails to hold the pre-installed cables for that rack unit in place. In two steps, the image shows how the Velcro straps are first removed from the bundle of cables, after which the cable tray is unscrewed from the rails.
