Prepare the MX480 Router for the SCBE2-MX Upgrade
1.
Verify that the system runs Junos OS Release 13.3 or later by issuing the show version
command on the master router.
user@host> show version
Model: mx480
Junos Base OS Software Suite [13.3-yyyymmdd];
...
NOTE: The SCBE2-MX is supported only on:
•
Junos OS Release 13.3 or later
• Network Services Mode: Enhanced-IP
The latest software ensures a healthy system—that is, a system that comprises Routing
Engines, control boards, and FPCs—before the upgrade.
For information about how to verify and upgrade the Junos OS, see the Junos OS
Installation and Upgrade Guide .
Power Off the MX480 Router
NOTE: After turning off the power supply, wait at least 60 seconds before
turning it back on.
1.
On the external management device connected to the Routing Engine, issue the
request system halt both-routing-engines operational mode command. This command
shuts down the Routing Engines cleanly, so that their state information is preserved.
(If the router contains only one Routing Engine, issue the
request system halt
command.)
user@host> request system halt both-routing-engines
2.
Wait until a message appears on the console confirming that the operating system
has halted.
3.
Attach an electrostatic discharge (ESD) grounding strap to your bare wrist and connect
the strap to one of the ESD points on the chassis.
4.
Move the AC input switch on the chassis above the AC power supply or the DC circuit
breaker on each DC power supply faceplate to the off
(O)
position.
