Description

Cabletron MMAC PSM Power Supply Module MMAC-8 MMAC-8FNB

This is an original equipment manufacturer (OEM) power supply module from Cabletron, designed specifically for the MMAC-8 and MMAC-8FNB modular network switching chassis. The PSM (Power Supply Module) is an essential component in these multi-purpose access concentrator systems, providing reliable power distribution to the chassis backplane and connected line cards.

Specifications & What's Included

  • Brand: Cabletron Systems
  • Model: MMAC PSM
  • Type: Modular Power Supply Module
  • Compatible Chassis: MMAC-8, MMAC-8FNB
  • OEM part for legacy network switching systems
  • Module form factor for installation into compatible chassis
  • Pulled from a working network environment

Applications

The Cabletron MMAC series was a widely deployed modular access concentrator platform used throughout the 1990s and early 2000s in enterprise networks, service provider core networks, and mid-market data centers. The MMAC-8 and MMAC-8FNB chassis supported up to 8 line card slots and were known for flexibility and reliability in multi-protocol networking environments. The PSM power supply module is the critical component that energized the entire chassis and its installed cards—including Ethernet, Token Ring, FDDI, and ATM modules. Organizations maintaining legacy Cabletron equipment or building vintage network labs often require replacement power supply modules to restore or expand these systems. This is genuine OEM Cabletron hardware, not a third-party substitute.
