Removing an MCS from an M40e Router
To remove an MCS from an M40e router:
1.
Place an electrostatic bag or antistatic mat on a flat, stable surface.
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.
Remove the rear component cover by loosening the thumbscrew at each corner of
the cover and pulling it straight off the chassis. For complete instructions, see
“Removing Components from the Chassis Before Installing the M40e Router Without
a Lift” on page 83.
4.
If two host modules are installed, use one of the following two methods to determine
which is functioning as master:
•
Note which of the green host module
MASTER
LEDs is lit on the craft interface.
•
The master Routing Engine is designated
Master
in the
Current state
field when you
issue the command:
user@host>
show chassis routing-engine
Routing Engine status: Slot 0: Current state
Master ...
5.
If the component you are removing belongs to the master host module and a second
host module is installed, switch mastership to the standby host module by issuing
the CLI command:
user@host>
request chassis routing-engine master switch
