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. Click the Device tab.
2. Click the UPS icon.
3. Click the UPS Settings button.
4. Perform the following actions as required:
• Verify the Current UPS Communication method. See Note 1:
• SNMP – Network connection.
• Serial – Serial connection.
• Unknown – No connection.
• Choose a Detection Setting from the dropdown menu: 
• 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.
• 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 
connections, but not a combination of both methods.
Note 2: Detection Setting must be set to Auto. If a UPS is detected, the 
setting changes to Enable.
Note 3: The maximum recommended Loading Ratio varies among models of 
UPS units. The general range is 60% to 80%.
Note 4: To specify UPS units by DNS names, ask your IT administrator to 
add the DNS names to the DNS server, before you make UPS settings.
