This chapter describes how to install additional cards and replace existing cards and other units in the
SmartEdge
®
1200 chassis.
The design of the SmartEdge 1200 router permits you to install and replace all cards without powering off
the system.
Note
In the descriptions that follow, the term SmartEdge 1200 applies to any version of the chassis,
unless otherwise noted. The terms SmartEdge 1200s and SmartEdge 1200n refer to the
standard and NEBS-compliant versions of the chassis, respectively. Figures for the
SmartEdge 1200 chassis illustrate the SmartEdge 1200n chassis, unless otherwise noted.
In the descriptions that follow, the term controller card refers to any version of the
Cross-Connect Route Processor (XCRP) Controller card (XCRP, XCRP3, XCRP4), unless
otherwise noted.
The term Gigabit Ethernet applies to any Ethernet traffic card that supports a port speed of
1 Gbps or greater; unless explicitly stated, the speed of any Gigabit Ethernet port is 1 Gbps.
Note
After you replace a traffic card or change its physical configuration, you must enter
SmartEdge OS commands from the command-line interface (CLI) to restore the card to
normal operations.
Caution
Risk of equipment malfunction. If you install or replace a card in a running system and the
system is not fully operational, you can cause the system to malfunction.
To reduce the risk, make sure the system is fully operational before proceeding with the
installation or replacement procedure:
1. In a system with dual controller cards, ensure that the standby controller is fully
synchronized with the active controller card. Use the
show redundancy
command (in any
mode) to display the status of the standby controller.
2. In a system with a single controller card, ensure that you have the CLI prompt on the
console.
If the system is not currently in an operational state, you need to power off the system. To
power off the system, remove all fuses for both power zones (primary and backup for each
zone) in the fuse panel.
