MTAS-192

June 2006 Installation Guide

Each MTAS shelf requires three (3) Rack Units or 5.25 inches of vertical rack space.

The MTAS shelves may be installed directly above or below one another: there is no

vertical spacing required for cooling or cabling.

2.8 Unpacking

The MTAS is shipped in two separate boxes – one contains the MTAS-192 shelf, and

the other contains the circuit packs for the shelf. There are no special handling

requirements for the shelf; however, the circuit packs require standard ESD handling

precautions.

CAUTION: A grounded wrist strap should be worn at all times when handling the circuit

packs. Place cards in or on static bags when working with the cards.

NOTE: After unpacking, do not install the circuit packs into the shelf before the shelf is

mounted in the equipment rack. Mount the MTAS-192 shelf in the rack before inserting

circuit packs.

2.9 Inspection

Step 1. Using standard ESD handling precautions unwrap circuit cards one at a time.

Step 2. Consult the packing list (see section 2.10 Packing List) to verify that all items

have been received as ordered and inspect them for obvious physical damage.

Step 3. If there is damage, re-pack the item in the shipping materials in which it came

in and return to Comtest Networks using the standard defect return procedure

in Appendix B: Repair and Return Services.

Step 4. If there is no damage, go to Chapter 3: Installing the MTAS Shelf.
