Description

10-32 x 5/8 in Pan Head SEMS Screw (12–21368–02)

Compaq recommends mounting the ECB shelf in the front
of the cabinet, directly above the lower BA370 enclosure.
This shelf is capable of holding two ECBs (a single or dual
ECB module). If only one ECB (a single or dual ECB
module) is installed, a blank bezel must be installed in the
other opening.
Note

CXO6635A

Angle Bracket
(74–60099–01)

If only one BA370 enclosure is installed within
the cabinet, the space above the ECB shelf must
be covered with 5U and 1U filler panels to
provide adequate air flow within the cabinet. If
two BA370 enclosures are installed, no filler
panels are required above the upper enclosure.
If two BA370 enclosures will be installed within
the cabinet, Compaq recommends installing the
ECB shelf prior to installing the second BA370
enclosure in the upper location. Otherwise, it
might be difficult to secure the rear ECB shelf
mounting brackets.

Installing the ECB Shelf

Table 2

Complete the procedure in Table 2 to install an ECB shelf
in a cabinet.

ECB Shelf Installation Procedure

Install two clip U-nuts in the rear leg of the left-front
cabinet rail, using holes 69 and 72.

Note
Count only the cabinet rail holes that are 0.281
inch in diameter, beginning at the bottom of the
cabinet. DO NOT count the first smaller hole at
the very bottom or top of the rail.

CXO6599A

Holding the angle bracket, align it with the holes
containing the U-nuts installed in the previous step and
secure the bracket using two 10-32 x 5/8 in Pan Head
screws.

Repeat steps 1 and 2 for the rear leg of the right-front
cabinet rail.

Insert four clip U-nuts in rail holes 68 and 71 on both
cabinet vertical rails.

Insert the ECB shelf into the angle brackets, align the
shelf with the four clip U-nuts installed in the previous
step and secure it using four 10-32 x 5/8 in Pan Head
screws (two on the left and right sides) finger-tight.

From the rear of the cabinet, secure the back of the ECB
shelf to the angle brackets by installing two 10-32 x 5/8 in
Pan Head screws (one in the upper hole of the left angle
bracket and lower hole of the right angle bracket—as seen
from the rear).

From the front of the cabinet, fully tighten the four screws
installed in step 5 that hold the ECB shelf to the cabinet
rails.

If only one ECB will be installed in the ECB shelf, install
the blank bezel into the open slot.
