Removing the ASN Component Tray
To remove the ASN component tray:
1.
Turn off the ASN, and detach all cables from the back panel.
2.
Using a Phillips screwdriver, loosen the two captive screws that fasten the tray to
the chassis (Figure 1).
3.
Pull the two captive screws and gently slide the tray out of the chassis.
Make sure to hold the sides and bottom of the tray to support it; try to keep the tray
level as you slide it out.
4.
Place the tray on a sturdy work surface.
You are now ready to replace or install the Fast Packet Cache module. Go to the
appropriate section:
• If you are replacing a Fast Packet Cache module with a new one, you must first
remove the old one. Go to “Removing the Fast Packet Cache Module.”
• If you are not replacing an old Fast Packet Cache module, go to “Installing the
Standoffs.”
Caution:
Do not touch any components or modules in the ASN until you have
attached an antistatic wrist strap. Refer to the section “Attaching the Antistatic
Wrist Strap.”
Note:
The net module ports are exposed at the back of the component tray. To
perform maintenance tasks on the ASN components, face the back of the tray.
