Chapter 5: Subsystem Maintenance
• Prior to replacing the controller module, it is imperative for your own
safety to be sure that no power is being supplied to the system.
5.2.2 Removing the Controller Module
To remove the controller module:
1. Make sure there is no data access to the subsystem to avoid losing any
data. Use the software provided on the host computer to stop all I/O
accesses to the FALCON II.
2. Power off the subsystem. Be sure to flush all cache data before
powering off the subsystem. Turn off both power switches on the rear
of the subsystem.
3. Disconnect all cables from the controller module. These include the
SCSI cables connecting to input/output SCSI connectors, Ethernet cable
connected to the LAN port, and any cables connected to the COM ports.
4. Remove the screws on the levers at the back of the controller module.

5. Remove the controller module. Once all the cables have been
disconnected, press down the two (2) levers at the back of the controller
module. The controller module will automatically be eased out of the
controller module bay. Gently pull the controller module out of the
subsystem. (See Figure 5-2)
