Remove/Install Filler Panel
PURPOSE
This procedure provides instructions to remove or install a filler panel.
GENERAL
The 1677 SONET Link uses a half-high slot filler panel and a full-high slot filler panel. See
figure 133-1. The filler panel is a metal plate that has two captive thumbscrews and special gasket
material along its edges. The panel minimizes electromagnetic interference (EMI) and also guides
airflow through the chassis for cooling.
The chassis, filler panels, access covers, and card front panels are part of a complete EMI-compliant
enclosure. Never operate the node with access covers or filler panels removed. If the node will be
operated with a card slot empty, install a filler panel over the opening. Failure to follow these
instructions will cause the equipment to violate part 15 of the FCC rules.
WARNING: Possibility of equipment damage. Make sure each empty card-cage slot is
covered with a filler panel whenever the 1677 SONET Link is turned on. This
is necessary so that the chassis cooling system performs as designed. Never
operate the 1677 SONET Link with an open empty card slot for more than
5 minutes at a time while servicing.
