I/O and Auxiliary Block Considerations
Keep the following considerations in mind when locating I/O
and auxiliary blocks:
1. An enclosure can contain more than one repeater mount-
ing unit. The units are typically located on the first column.
2. Position an auxiliary block directly above or below its I/O
block.
3. Install blank blocks in any empty slots to maintain air flow
through a block column. Blank blocks are not needed, how-
ever, to fill positions at the bottom of a column.
