These files can be transferred to the new compact flash by:
• copying the files from another compact flash to a PC and then transferring the files
to the new compact flash

new compact flash
Fan Module
The Fan module has eight fans mounted on its circuit board. The Fan module must always be
installed and fully operational while the 7705 SAR-8 is powered up. During routine
maintenance and Fan module replacement, the system can operate safely for up to
4 minutes without the Fan module installed. Figure 26 illustrates the installation of the Fan
module.
To maintain EMC compliance, cables that are shielded and grounded at both ends must be
used with the Alarm interface.
Refer to Fan Module Connectors and LEDs on page 130 for a description of the Fan module
LEDs.
Refer to Replacing the Fan Module on page 145 for information on replacing the Fan
module.
The Fan module provides an alarm interface equipped with relays that can be used to trigger
external alarm indicators. It also provides inputs that can be used to trigger the generation of
alarms on the 7705 SAR-8 that indicate environmental or external alarm conditions. Refer to
External Alarms Port Pinouts on page 154 for pinout definitions.
