Juniper EX3400 Features Guide

• alternate—Reboot from the alternate partition.
scc—(TX Matrix routers only) (Optional) Reboot the Routing Engine on the TX Matrix
switch-card chassis. If you issue the command from re0, re0 is rebooted. If you issue
the command from re1, re1 is rebooted.
sfc number—(TX Matrix Plus routers only) (Optional) Reboot the Routing Engine on the
TX Matrix Plus switch-fabric chassis. If you issue the command from re0, re0 is
rebooted. If you issue the command from re1, re1 is rebooted. Replace number with
0.
slice slice—(EX Series switches only) (Optional) Reboot a partition on the boot media.
This option has the following suboptions:
• 1—Power off partition 1.
• 2—Power off partition 2.
• alternate—Reboot from the alternate partition.
Additional Information Reboot requests are recorded in the system log files, which you can view with the show
log command (see show log). Also, the names of any running processes that are scheduled
to be shut down are changed. You can view the process names with the show system
processes command (see show system processes).
On a TX Matrix or TX Matrix Plus router, if you issue the request system reboot command
on the master Routing Engine, all the master Routing Engines connected to the routing
matrix are rebooted. If you issue this command on the backup Routing Engine, all the
backup Routing Engines connected to the routing matrix are rebooted.
NOTE: Before issuing the request system reboot command on a TX Matrix
Plus router with no options or the all-chassis, all-lcc, lccnumber, or sfc options,
verify that master Routing Engine for all routers in the routing matrix are in
the same slot number. If the master Routing Engine for a line-card chassis is
in a different slot number than the master Routing Engine for a TX Matrix
Plus router, the line-card chassis might become logically disconnected from
the routing matrix after the request system reboot command.
NOTE: To reboot a router that has two Routing Engines, reboot the backup
Routing Engine (if you have upgraded it) first, and then reboot the master
Routing Engine.
