Overview
AT-8400 blank faceplates are designed to maintain optimal, trouble-free
environmental conditions for the AT-8400 chassis. This installation guide
provides instructions for installing both the line card blank faceplate and
the power supply blank faceplate.
The AT-8400 chassis requires a blank faceplate installed in every chassis slot
that is not occupied by an Ethernet line card. The blank faceplate (see
Figure 1) keeps dust from getting into the switch and maintains proper
airflow throughout the chassis.

The AT-8400 chassis also requires a blank faceplate installed in any power
supply slot not occupied by a power supply. The power supply blank
faceplate (see Figure 2) ensures proper cooling and ventilation of the
AT-8400 chassis.

Installation Guide
Installing the AT-8400 Line Card Blank Faceplate
You can install an AT-8400 line card blank faceplate whether the chassis is
powered on or powered off.
Caution
Before installing an AT-8400 blank faceplate, refer to the
AT-8400
Series Switch Reference Guide
for electrical safety information.
To install an AT-8400 line card blank faceplate, perform the following
procedure:
1.
Select the slot in the AT-8400 chassis where you need to install a blank
faceplate. You can install the faceplate in any slot marked 1 through 12.
Caution
Do not install a blank faceplate in Slot M. Slot M is reserved for the
AT-8401 Management Fabric Card.
2.
Unpack a blank faceplate from the shipping package, and store any
unused blank faceplates in a safe location.
Caution
Observe all standard electrostatic discharge (ESD) precautions, such
as wearing an antistatic wrist strap, to avoid damaging the chassis
device. Line cards can be damaged by static electricity.
3.
Verify that the blank faceplate package includes all the items previously
listed in “Package Contents” on page 2. If any item is missing or
damaged, contact your Allied Telesyn sales representative for
assistance.
4.
Align the edge of the blank faceplate with the top and bottom guide
rails before carefully sliding the faceplate into the slot, as shown in
Figure 3. Slide the faceplate forward into the slot until the faceplate is
flush with the front of the chassis.

5.
Secure the blank faceplate to the chassis by using a Phillips screwdriver
to tighten the two installation screws on the faceplate.
Note
Always tighten the installation screws to secure the blank faceplate to
the switch chassis. Leaving a faceplate partially seated can still allow
dust to enter the chassis and disrupt the normal air flow.
You have completed the line card blank faceplate installation procedure.
