Installing a fanout panel
Install a fanout panel in a frame or rack to connect a 12-port DS3 or E3 FP to
customer premises signalling equipment.
Prerequisites
• You must be familiar with “Safety considerations and best practices”
(page 53).
• You will need a fanout panel with PEC NTHW52. The NTHW52 is pre-
assembled, including two adapter brackets fastened by four Phillips
screws to the panel mounting ears. See “A 12-port DS3 or E3 fanout
panel” (page 464).
• For fanout panel connections refer to 241-1501-200 Passport 15000,
20000 Hardware Description.
Procedure steps
1 Unpack the fanout panel from the container.
2 Place the front of the panel against the frame uprights so that it aligns with
the previous top holes in the brackets with the holes in the frame. The
panel has key-hole pins that align with the holes in the frame.
3 Hold the panel in one hand so that:
• the label TOP is at the top of the panel
• the Phillips screw heads of the adapter brackets face you
• the bracket holes are nearest you on the left and right and the BNC
connectors are farthest from you
4 While holding the panel in position, fasten a thread-forming 10-mm
(3/8-in.) hex-head screw through the upper left and the upper right
mounting holes. Leave the screws close to being seated.
5 Align the other bracket holes on the panel with the frame holes under the
grounding strip.
6 Loosely tighten the remaining 2 screws.
7 Tighten all screws to snug plus a 1/4 turn.
