Installing the Tellabs 7300 Shelf
5.22 The Tellabs 7300 NE may be installed in either a 19-inch datacom rack,
ETSI rack, or 23-inch North American seismic rack with mounting ears by
performing the steps below. Use the appropriate mounting kit for the rack type.
Refer to Table 4.1, page 2-25 for NEBS and ETSI Shelf Adapter Kits for the Tellabs
7345 Switch and to Table 4.6, page 2-35 for NEBS and ETSI Shelf Adapter Kits for
the Tellabs 7325 Switch.
__ 1. Install the left and right side brackets, each with screws provided in the
kit.
__ 2. Install the Tellabs 7300 NE in the desired rack position. Fasten it with
screws provided in the kit.
Installing the Fuse Panel (Optional)
5.23 The Fuse Panel (Tellabs part number 81.71020FP5-5-R5) is an optional
power distribution panel that can be installed to distribute power to the Tellabs
7300 NEs and is typically installed at the top of the relay rack. Refer to Figure 5.1,
page 2-49.
5.24 Up to two power cables (A-side and B-side) are required for each
shelf/unit. The Power cable kit (Tellabs part number 81.7300PCBLB-R5 for the
Tellabs 7345 Switch and Tellabs part number 81.7325PCBLB-R5 for the Tellabs
7325 Switch) can be used.
Warning:
The Tellabs 7300 NE takes air in from the left of the shelf and expels heated air
through the right side, and this airflow increase must be considered when you
design the placement of the shelf and surrounding equipment. If the surrounding
temperature exceeds the nonoperating temperature limit, physical damage to
the shelf may occur, even if the modules are not operating.
