Removing Filler Brackets
Filler brackets cover empty ASN net module positions and the openings above
positions 1 and 3 (Figure
1-2). When you install a net module, you must remove
the filler brackets not only from the position in which you want to install the net
module, but also from the openings above positions 1 and 3.
To remove a filler bracket, grasp its top edges. Then lift the bracket up and toward
the front of the tray to release the metal tabs.

Removing a Net Module
Read this section if a net module already occupies the slot you want to use. To
remove a module from position 2 or 4 (Figure
1-2), you must first remove the
filler bracket and net module (if any) above it. See the previous section,
“Remo
ving Filler Brackets.”
Note: This manual refers to the end of the component tray where the net
module ports are exposed as the “back end” of the tray. To perform
maintenance tasks on the ASN components, you face the back end of the tray.
Caution: Do not touch any components or boards in the ASN until you have
attached the antistatic wrist strap.
