Removing a QFX10000 Routing and Control Board

Copyright © 2019, Juniper Networks, Inc.
The QFX10000 line of modular chassis can have one or two Routing and Control Boards
(RCBs), depending on the configuration. RCBs can be installed in either of the two top
slots on the front of the chassis.
In redundant configurations, a QFX10000 RCB is a hot-removable and hot-insertable
field-replaceable unit (FRU). In base configurations, you need to install a second RCB
before removing a failing RCB in order to prevent the switch from shutting down. We
recommend that you take base systems offline before replacing the RCB.
Before you remove an RCB, ensure that you have an electrostatic discharge (ESD)
grounding strap.
CAUTION: In base configurations, removal of the RCB causes the system to
shut down. In redundant configurations, removal of the RCB causes the
system to reboot and start the election process for a new master.
To remove an RCB:
Take the RCB offline.
