Upgrading the System
You can upgrade your system software to a new release of the PARTNER ACS by using a PCMCIA card. You also can add or replace modules and add lines, pools, and extensions.
Both old and new (introduced in system Release 4.0) 5-slot carriers are compatible with PARTNER ACS R7.0.
Battery Replacement 10
The processor module uses two user-replaceable AAA alkaline batteries. These batteries provide enough power to retain the system programming settings during a power failure for 45 days to six months, depending on the freshness of the batteries. When battery power is getting low, the system displays a ChgBat W/PowerOn or ReplaceSysBat W/Power On message on the top line of display telephones at extensions 10 and 11 in place of the default day/date/time message. Users at these extensions should notify the System Administrator when they see this message. You should replace the batteries within 45 days of seeing the message.
The message may flicker on and off as the batteries approach the low-power threshold.
Do not turn off the power or remove the processor module before replacing the batteries! If you do, all settings for system and telephone programming revert to the factory settings. If you have a Backup/Restore PC Card, do a backup before changing the batteries.
PARTNER ACS Release 7.0 supports the PARTNER Remote Access PC Card, which allows you to program the system remotely and perform backup and restore functions.
