Product Details Introduction

Silicon Graphics 99-80461-01 Power Board

99-80461-01 is an SGI original high-end workstation/server redundant power backplane/distribution board, responsible for multi power parallel connection, load balancing, and system power interaction. It is commonly used in the Onyx/Challenge series.

Model: 99-80461-01 (SGI original power backplane)

Type: Redundant power distribution board, non independent power supply module

Compatible models: SGI Onyx, Challenge series rack mounted workstations/servers

Function: Multi power input collection, load balancing, fault switching

Input: Supports 2-4 sets of SGI dedicated hot swappable power modules

Output: Unified 12V/5V bus, supplying power to the system motherboard/backplane

Monitoring: Onboard power supply in place, voltage, temperature, and fan speed monitoring

Protection: Automatic isolation for single power failure, ensuring the machine does not shut down

Communication: Connect with the system management board and report the status of the power pack

Interface: dedicated power socket, system bus, alarm contacts

PCB: Industrial grade multi-layer board, high current copper foil design

Heat dissipation: passive heat dissipation+forced air cooling of the chassis, suitable for high loads

System adaptation: IRIX 6. x, native support for power redundancy management

Status: Discontinued and scarce, mainly for disassembly/refurbishment, core spare parts for maintenance of large SGI equipment

Usage: Onyx/Challenge high-performance graphics workstation, industrial server, large-scale simulation system
