BLK-100 Installation
Purpose/Scope
This procedure gives the steps required to install a blank block
(BLK-100) to fill empty block positions. Any empty positions
within a column of blocks must be filled to maintain airflow.
Blank blocks are not required, however, in empty positions at
the bottom of a column.
The procedure is the same whether installing a nonredundant
or redundant blank block. A redundant blank block, however,
requires a redundant mounting column.
Parts
None.
Tools
•
Flat-blade or Phillips screwdriver.
Procedure
□
1. Install the block base.
a. Position the base on the mounting column. Insert the
tabs at the back, left side of the base into the slots in the
column as shown in Figure
PR5-1 . The base is properly
positioned when the posts on the back of the base line up
with the alignment holes in the column. The mounting col-
umn connectors should protrude through the base.
b. Tighten the two captive screws to attach the base to the
column. A redundant base has four captive screws.
c. Verify the back of the base is flush with the mounting
column.
□
2. Install the blank module.
a. Grasp the retractable handle when inserting the blank
module. Insure the handle is extended completely so that
the fastening screw does not stick out from the back of the
module (Fig.
PR5-2 ).
b. Position the blank module on the base. The module is
properly positioned when the posts protruding from the
5 min.
