Municipal Backup Power: What Should Your UPS Keep Running?

Give battery backup a specific job

Imagine a township office loses power. A counter computer stays on because it has battery backup, but the application cannot connect: the network cabinet has gone dark. Keeping one device running has not kept the resident’s task available. Start your power review with the work that needs to continue or close safely.

An uninterruptible power supply, or UPS, provides temporary battery power to connected equipment. NIST’s contingency planning guide describes appropriately sized UPS equipment as a short-term power measure. For a Michigan township, village, or city, define the purpose clearly: ride through a brief interruption, allow an orderly shutdown, or bridge to an agreed longer-term power arrangement.

Trace the equipment behind the task

Choose one priority workflow, such as reaching an office application or handling ordinary office calls. Have IT identify the devices it depends on: workstation, network switch, firewall, internet equipment, and any local server or storage. Record where each device gets power and which UPS, if any, supports it. Include separate closets or buildings in that map.

If a phone or wireless access point receives power from a network switch, include that switch in the review. Ask IT to confirm the approved connections and label the protected equipment. Also record limitations outside the building, such as an unavailable provider service. Local battery power cannot establish that every outside dependency remains available.

Review capacity and runtime separately

Capacity describes how much connected equipment a UPS can support. Runtime describes how long its batteries can support a given load. Eaton’s network closet guide distinguishes these questions and explains that adding battery packs does not increase a UPS’s power rating. A larger advertised VA number alone does not tell staff how many minutes their equipment will run.

Ask IT to record the actual connected load, check the unit’s watt and VA ratings, and use the manufacturer’s runtime information for the intended configuration. Allow for planned equipment additions. Request a documented estimate with its assumptions, including battery condition. When a new switch or server is added, revisit the power plan along with the network diagram.

Agree on shutdown and the return to service

A battery provides a limited window for decisions. Ask which systems have compatible shutdown software or management connections, what actions are configured, and which steps require an authorized person. Schneider Electric’s UPS guide describes both temporary operation and time for orderly shutdown. The presence of a UPS does not show that a server’s automatic shutdown has been configured or tested.

Have IT and the application owner agree on the shutdown sequence and when staff should stop starting new work. Document how service resumes after power returns, including who checks applications and confirms the office can use them. Coordinate any generator arrangement with the responsible facilities team and equipment providers. Keep the staff instructions focused on the decisions they need to make.

Keep battery care and alerts assigned

Record each UPS model, location, battery type, installation or replacement information, and maintenance contact. Follow the guidance for that exact equipment. Schneider Electric’s guidance for APC VRLA batteries identifies temperature, load, age, and discharge history as factors affecting performance. Avoid treating a battery’s original runtime estimate as a permanent capability.

Find out which alerts the installed model can provide and who receives them. If notifications depend on a network connection, ask how the relevant equipment remains powered and what happens if that connection fails. Give staff a known contact for an alarm or reported battery fault. Keep maintenance findings and unresolved issues with the support record so a warning receives a clear follow-up.

Use a planned test with clear limits

Arrange testing with IT, affected staff, and facilities where needed. Agree on the scope, timing, stopping point, and recovery steps before interrupting service. Let the responsible technical team choose the manufacturer-approved procedure. A UPS self-test, runtime calibration, and full workflow exercise answer different questions; record which procedure was used and what it established.

Schneider Electric cautions that unnecessary runtime calibrations and repeated deep discharges can shorten the life of APC VRLA batteries. Testing should follow the model’s guidance and an agreed schedule. After the exercise, confirm normal power, the required battery recharge, and application availability. Use the findings to correct the equipment map, shutdown plan, or maintenance work.

Bring this checklist to your next IT review

Choose one municipal building and ask your Michigan IT services provider to review its UPS inventory with the people who use the supported systems. Start with one important workflow and document the answers in plain language.

• What must keep running, and what must have time to shut down?
• Which devices and power connections support that complete task?
• Do capacity and runtime estimates match the actual load and battery condition?
• Who manages shutdown, restart, battery maintenance, and alerts?
• What does the approved test establish, and how will normal service be confirmed?
• Which equipment changes or unresolved findings require another review?
