Making UPS Settings
These settings control how the VTrak subsystem detects the UPS unit and
responds to data reported by the UPS unit.
To make UPS settings:
1. From the Main Menu, highlight Additional Info and Management and press
Enter.
2. Highlight UPS Management and press Enter.
3. Highlight UPS Settings and press Enter.

• Verify the Current UPS Communication method. See Note 1:
• SNMP – Network connection.
• Serial – Serial connection.

• Automatic – Default. If a UPS is detected when the subsystem
boots, the setting changes to Enable.
• Enable – Monitors UPS. Settings changes, reports warnings, and
logs events.
• Disable – Monitors UPS only.
• Type values into the Threshold fields. See Note 2:
• Running Time Remaining Threshold – Actual time below this
value resets adaptive writeback cache to writethrough.
• Warning Temperature Threshold – Actual temperature above this
value triggers a warning and logs an event.
• Loading Ratio Threshold – Actual loading ratio (percentage)
above this threshold triggers a warning and logs an event. See
Note 3.
• Battery Charge Remaining Threshold – Reserve capacity below
this percentage triggers a warning and logs an event.
• For UPS units with network cards, type the IP addresses or DNS names
in fields UPS 1 and UPS 2. See Note 4.
5. Press Ctrl-A to save your settings.
Note 1: VTrak supports multiple UPS units using network or serial
