How To Remotely Monitor A UPS System
24-7 remote monitoring uses Simple Network Management Protocols (SNMP) to enable the performance of UPS systems to be analysed by dedicated, expert personnel.
The UPS uses network communications cards and dedicated management software to transmit highly-secure SSL encrypted data to the network. This information can include load levels, input and output voltage, and battery voltage.
Most modern uninterruptible power supplies will also perform automated self-testing every 24 hours and alarm if a fault occurs. If a fault or failure is detected, the remote monitoring software triggers automated email or SMS notifications which are picked up by trained technical experts, who can carry out further diagnostics, arrange for engineers to fix the more serious incidents, or in the worst-case scenario initiate automatic shutdown procedures.
Remote UPS monitoring is particularly useful for dealing with alarms outside of normal working hours, for unmanned sites, or for enterprise-wide networks with UPS spread across several locations.
SNMP-based remote monitoring also enables the historical tracking of UPS performance over time, which can be used to identify areas for improvement to optimise system operation.
This is because the network-connected computer’s storage and processing capacities are far greater than the UPS’s internal processor, which only allows engineers to diagnose potential problems based on recent events.
One of the key roles of UPS remote monitoring is to detect – and solve – any faults before they have the chance to develop into something more serious.
For example, a failed battery self-test would trigger an automated alarm, which under further investigation is caused by a weakening battery block. Promptly replacing this block would reduce the risk of the entire battery set failing.
