Installing an AT-LX3801 Blank Slot Cover
The AT-LX3801 Blank Slot Cover protects the fiber optic connectors on
the backplane from becoming dirty, and helps maintain proper air flow
through the chassis.
Note
Allied Telesyn strongly recommends that a blank slot cover be
inserted in any slot that does not contain a functioning line card.
To install a blank slot cover, perform the following procedure:
1. Remove the AT-LX3801 Blank Slot Cover from its shipping package
and store the package in a safe place.
You must use the original package if you need to return the unit to
Allied Telesyn.
2. Select the slot in the AT-LX3800U chassis where you want to install
the blank slot cover.
3. If an AT-LX3811/x line card is installed in the slot, do the following:
a. Disconnect the cables from the SFP in the line card.
b. Reinstall the SFP port dust cap.
c. Remove the line card from the slot.
4. Locate the left and right alignment guides in the slot, as shown in
Figure 28.
