Installing the
Front Plate Be sure to install a front plate in slots without a line card to improve the air-cooling
efficiency of the main unit and to suppress the radiation of noise.
1. Install the front plate into the line card slot.
2. Tighten the screws on the left and right of the front plate to fix the front plate
in place.
Figure 10-15: Inserting the Front Plate
Do not insert a hand into an idle slot to prevent injury from sharp guide rail
corners, etc.
Be sure to install a front plate over a slot not containing a line card. With-
out the front plate, the slot will hinder proper cooling and may cause a fail-
ure.
Removing the
Front Plate 1. Remove the screws on the left and right of the front plate that are fixing the
front plate in place.
2. Remove the front plate.
