Installing an MX480 AS MLC
You can install up to five Application Services Modular Line Cards (AS MLCs) horizontally
in the front of the MX480 router. The AS MLCs are hot-insertable and hot-removable.
An empty AS MLC weighs 10.5 lb (4.76 kg). A fully configured AS MLC can weigh up to
15.27 lb (6.93 kg). Be prepared to accept its full weight.
To install an AS MLC (see Figure 131 on page 311 ):
1.
Attach an ESD grounding strap to your bare wrist and connect the strap to one of the
ESD points on the chassis.
2.
Place the AS MLC on an antistatic mat.
3.
Take the AS MSC and AS MXC (the modular cards) to be installed in the AS MLC out
of its electrostatic bag. The AS MSC must be inserted in the left slot and the AS MXC
in the right slot.
4.
Install the AS MSC and AS MXC into the appropriate slot on the AS MLC.
