9 – Power Module Status and Replacement

Warning: Only authorized Tripp Lite service technicians with knowledge and operational training of this equipment should install, repair or remove any system components, including power modules. Only power modules with the same firmware versions may be placed within the same UPS system frame. Verify power module firmware version before replacement. Permanent power module removal or addition can only be performed by Tripp Lite authorized service technicians.

9-1 Power Module Features and Status

Each Power Module features an LED indicator to inform the user of its status.

LED Indicator Statuses

“ON”—The power module is active and functioning properly. “FLASHING”—The power module has failed and is offline.

“OFF”—When the locking latch is in “UNLOCKED” () position, the power module is inactive.

When the locking latch is in “LOCKED” () position and the main power is on, the power module has failed.

9-2 Preliminary Replacement Checklist

•Before removing a Power Module, ensure that the remaining Power Modules can support the connected load.

•Verify that the Power Module needs service or replacement via its individual LED status indicator.

•Do not attempt to remove Power Modules by yourself. Power Modules weigh 30 kg (66 lb) and require at least two people for proper handling.

•Power Modules can be replaced in any UPS Operating Mode. It is not necessary to power loads off or leave them unprotected. Note: UPS must be able to support load without the Power Modules to be replaced. If the UPS cannot handle the load once the Power Module is deactivated, an overload will occur and the UPS will shut down.

•Replace power modules with same firmware version only.
