Replacing The Standard Cbs In The T-Series Routing Platform; Connecting An Offline T-Series Routing Platform To The Jcs 1200 Platform - Juniper JCS 1200 Hardware Manual

Replacing the Standard CBs in the T-series Routing Platform

Before you connect an offline T-series routing platform to the JCS 1200 platform,
you must replace the standard control boards (CBs) with T-CBs. To replace the CBs
with T-CBs:
1.
2.
3.
NOTE: The CBs and T-CBs are hot-removable and hot-insertable if the routing node
contains redundant host subsystems. However, we recommend that you power off
the routing platform before you replace the CBs and T-CBs.

Connecting an Offline T-series Routing Platform to the JCS 1200 Platform

After you replace the CBs with T-CBs, you connect each T-CB on the T-series routing
platform to each switch module on the JCS 1200 platform. Figure 32 on page 76
shows the location of the switch modules on the JCS 1200 platform.
If the routing platform is powered on, issue the
both-routing-engines operational mode command from the console or other
management device connected to the routing platform. The command shuts
down the Routing Engines cleanly, so their state information is preserved.
user@host> request system halt both-routing-engines
Wait until a message appears on the console confirming that the operating system
has halted. For more information about the command, see the JUNOS System
Basics and Services Command Reference.
Attach an electrostatic discharge (ESD) grounding strap to your bare wrist and
connect the strap to one of the ESD points on the chassis.
Switch all circuit breakers on the power supply faceplates to the off position (
Set the switches on each T-CB:
Set the chassis ID switch to 0. You must use the same chassis ID on each
T-CB.
Set the M/S switch on the T-CB faceplate to
Replace each CB with a T-CB. Use the standard replacement procedure described
in the hardware guide for your routing platform.
You can optionally upgrade the Routing Engines in the routing platform. To
replace each Routing Engine, follow the standard replacement procedure
described in the hardware guide for your routing platform.
