Juniper Networks MX480 - Manual (Page 240)

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 112 on page 217 ):
1. Attach an electrostatic discharge (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.
5. Locate the slots in the card cage in which you plan to install the AS MLC.
6. Orient the AS MLC so that the faceplate faces you.
7. Lift the AS MLC into place, and carefully align the sides of the AS MLC with the guides
inside the card cage.
CAUTION: When the AS MLC is out of the chassis, do not hold it by the
ejector handles, bus bars, or edge connectors. They cannot support its
weight.
8. Slide the AS MLC all the way into the card cage until you feel resistance.
9. Grasp both ejector handles, and rotate them clockwise simultaneously until the AS
MLC is fully seated.
10. Use one of the following methods to bring the AS MLC online:
• Press and hold the AS MLC online/offline button until the green OK LED next to the
button lights steadily, in about 5 seconds. The LEDs and online/offline button for
each AS MLC are located above it on the craft interface.
• Issue the following CLI command:
user@host> request chassis fpc slot slot-number online
For more information about the command, see the Junos OS Operational Mode
Commands.
CAUTION: After the OK LED lights steadily, wait at least 30 seconds before
removing the AS MLC again, removing an AS MLC from a different slot, or
inserting an AS MLC in a different slot.
