Removing an MX480 AS MLC
When you remove an Application Services Modular Line Card (AS MLC), the router
continues to function, although the modular cards (AS MXC and AS MSC) installed on
the AS MLC being removed no longer function.
Up to five AS MLCs can be installed 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 remove an AS MLC (see Figure 111 on page 215 ):
1. Have ready a replacement AS MLC or an AS MLC blank panel and an antistatic mat
for the AS MLC.
2. Attach an electrostatic discharge (ESD) grounding strap to your bare wrist, and connect
the strap to one of the ESD points on the chassis.
3. Use one of the following methods to take the AS MLC offline:
• Press and hold the AS MLC online/offline button. The green OK LED next to the
button begins to blink. Hold the button down until the LED goes out. The
online/offline button for each AS MLC is located directly above it on the craft
interface.
• Issue the following CLI command:
user@host> request chassis fpc slot slot-number offline
For more information about the command, see the Junos OS Operational Mode
Commands.
NOTE: The slot number corresponds to the lowest numbered slot for
which the AS MLC is installed.
4. Simultaneously turn both the ejector handles counterclockwise to unseat the AS MLC.
5. Grasp the handles, and slide the AS MLC straight out of the card cage halfway.
