Installation of Controller Card Smart 16e Shelf User Manual

Fuses

There are two fuses located on the rear panel. Fuse one (F1) corresponds to power supply 1 (left slot), and

fuse two (F2) corresponds to power supply 2 (right slot). See Specifications and Features on page 53 for

fuse ratings.

AC/DC Power

The single and dual AC versions, illustrated in Figure 3 on page 27 and in Figure 4 on page 28, each have

captive 8-foot power cords. The power cords are terminated by a three-prong plug which connects to a

grounded power receptacle. The grounded power receptacle should be installed near the shelf and be easily

accessible. The power receptacle should also have suitable disconnect devices that are provided as part of

the building wiring. The power receptacle should be properly grounded. The protection of the

telecommunications network relies on the protective grounding of the Smart 16e Shelf.

The single DC version, illustrated in Figure 5 on page 29, provides a 3-position screw terminal block for

connection to a -48V source. The dual DC version, illustrated in Figure 6 on page 30, provides a 5-position

screw terminal block for connection to two -48V sources. In both DC versions, the last position is frame

ground.

See Appendix A, Pinouts, on page 51 for the pin assignments for the DC power supply.
