NOTE:

To provide the highest level of redundancy, use a fuse panel

with redundant (A and B) fuse positions or two separate fuse

panels for the A and B power supplies.

Table 3-2 Dual-line Shelf Power Supplies

NOTE:

When HDM 2180 or HDM 2182 modules are used in a Dual-

line shelf, installation of two external power supplies is

recommended. If an NCM 2000 is added to a Dual-line shelf

with an HDM 218x module, the use of two power supplies is

required.

NOTE:

The PWR 2940 power supply is recommended for use

only

110 volts. The PWR 2950 power supply can be used with

voltages of 100 to 240 Vac.

Hardware

Dimensions

AS2000 shelves require a mounting surface that can support the

weight of the shelf and all associated plug–in modules. A 19–inch

(49 cm) or 23–inch (59 cm) equipment rack, cabinet, or desktop can

support the weight of Access System 2000 shelves. Multi-line,

Quint-line, and Dual-line shelves can be front or mid-mounted into

a 19– or 23–inch (49 to 58.5 cm) rack.

Table 3-3 Approximate Weight and Height in Rack

NOTE:

Provide approximately 30 inches (77 cm) of clear space in

front of and behind the equipment rack for installers to

maneuver during assembling and testing.
