Core Functions

1. AC power front‑end gateway: Accepts site wide‑range AC mains input, performs filtering and surge protection, delivers conditioned AC power to 106M1079‑01 power supply main card.
2. Redundancy support: Supports dual‑PIM+dual‑PSU N+1 redundant power architecture to improve 3500 rack system availability.
3. Input‑side fault protection: Isolates AC‑side surge and over‑current faults, avoids damaging downstream power‑conversion main card and other monitoring modules.
4. Visual health diagnosis: OK LED quickly indicates AC input power and PIM module operational status for field maintenance.
5. Rack power subsystem cooperation: Works with 106M1079‑01 to generate ±5 V, ±15 V, 24 VDC multi‑rail power for all vibration‑monitoring and protection cards inside 3500 rack.

Installation, Replacement & Critical Warnings

1. For non‑redundant single‑power rack, fully de‑energize upstream AC input before replacement. Hot‑swap is only allowed when redundant power is configured.
2. Must pair with matching 106M1079‑01 universal AC power main card; legacy HV‑AC / LV‑AC power units are incompatible with this PIM, cannot be mixed‑used.
3. Torque AC input screw terminals to specified torque value; loose terminals produce overheating and intermittent rack power drop‑out.
4. After installation, check OK LED status, verify 3500 rack boots normally, complete module configuration download via 3500 Rack Configuration software.

5. Common failure mode: AC‑side electrical surge damage to input circuit. Investigate site AC power quality and check upstream fuse when PIM OK LED goes off and whole rack loses power.
