Installing the Server Into the Cabinet en-19
Note – Four screw holes are provided in the outer slide. Depending on the cabinet
depth, you may need to move one (or both) of the 10-32 screws to another of the four
screw holes. Be sure to use both screws to secure each rear bracket to the outer slide.
d. Tighten the two 10-32 screws and lock nuts on each slide to resecure the rear
brackets to the outer slides.
Determine the Vertical Position of the Server in
the Cabinet
Plan to install the tray assembly in the lowest available position in the cabinet. If you
are installing two Sun Fire 880 servers in the cabinet, install the lower server first.
To determine the vertical position of the server, identify which cabinet rail holes to
use for attaching the front and rear brackets by completing the following steps:
1. Locate and mark the correct holes on the right and left front vertical cabinet rails.
Make sure there is enough vertical space to install the server.
Note – Each Sun Fire 880 server requires 17 rack units (29.75 inches) or 51 holes on
the vertical rails of the cabinet. A standard 72-inch high cabinet can accommodate
two Sun Fire 880 servers.
If the Sun Fire 880 server will be installed immediately above a power sequencer,
leave at least one free hole above the sequencer.
Using masking tape or a felt tip pen, mark the lowest available hole for installing the
tray on the right front vertical rail of the cabinet. The second free hole is the lowest
available hole if you are installing the Sun Fire 880 server immediately above a
power sequencer.
Mark the matching hole on the left front rail of the cabinet. Count the holes to be
sure you are using matching holes on the right and left rails of the cabinet.
2. Locate and mark the corresponding holes on the right and left rear vertical cabinet
rails.
Using masking tape or a pen, mark the matching holes on the right and left rear
vertical rails.
Count the holes to be sure you are using the holes that match the ones you marked
in step 1.
