CLON cluster equipped with two big SYMMETRA RM 6000 Single-phase UPSes from APC Corporation. These UPSes are multi-battery systems. In case of something wrong with UPSes follow the instruction of UPS Troubleshooting.

Smaller UPSes ...

All UPSes are connected to emergency generator.

All connections (ether via Web interface or SSH) allowed only from local subnet.

SYMMETRA RM 6000 firmware upgrade

Enable SYMMETRA FTP service using its web interface. Download appropriate firmware from http://www.apc.com/ web site. Search not for SYMMETRA but for 'UPS Network Management Cards'. Last time apc_hw02_aos334_sy331.exe was used, it was listed as 'Network Management Card v3.3.1 Firmware Executable for Symmetra Single-Phase UPS with AP9617/8/9', part number SFSY331, file date 01/23/2007. To install, place it into CUE home directory, run metaframe and click on firmware file. Several files will be installed, upgrade program will be started and text GUI will shows up. Type SYMMETRA IP and admin username/password, start firmware installation and wait several minutes for completion. Repeat for all SYMMETRA devices (currently we have 2 of them). Remove all installed files from CUE home directory.

PowerChute Network Shutdown

That free software is used to shut down computers when UPS is running out of charge. Can be downloaded from http://www.apc.com/.
