To replace a cable connected to a management console or auxiliary device:
1. Attach an ESD grounding strap to your bare wrist and connect the strap to one of the
ESD points on the chassis.
2. Press the tab on the connector, and pull the connector straight out of the port.
3. Disconnect the cable from the console or auxiliary device.
4. Plug the RJ-45 end of the replacement serial cable into the CONSOLE or AUX port.
Figure 118 on page 293 shows the external device ports on the Routing Engine.
5. Plug the female DB-9 end into the console or auxiliary device's serial port.

Upgrading to the RE-S-X6-64G Routing Engine in a Redundant Host Subsystem
A redundant host subsystem consists of a master Routing Engine (RE0) and a backup
Routing Engine (RE1). To upgrade the host subsystem to use the RE-S-X6-64G Routing
Engine, you must first uninstall the backup Routing Engine and install the RE-S-X6-64G
Routing Engine, which then becomes the backup Routing Engine. You then switch over
this backup Routing Engine to make it the master Routing Engine. Replace the other
Routing Engine and configure it as the backup Routing Engine.
