GM6-DMMA

Description

Blanking/dummy module for GM6 chassis; used to fill unused module slots to protect the backplane and contacts.

The Polar Energy Assessment:

The GM6-DMMA is the manufacturer recommended blanking plate/dummy module for any unused GM6 slot. It prevents dust and foreign objects from entering the backplane, helps maintain cabinet airflow patterns, and avoids accidental contact with exposed connectors during maintenance. Sellers and OEM docs list DMMA as the official dummy for GM6 racks, and it’s a cheap piece of insurance for long-term reliability.

Pros

• Low cost, prevents dust and accidental contact with backplane contacts.
• OEM form factor ensures it fits properly and retains mechanical integrity of the rack.

Limitations

• No electrical function; purely mechanical protection.

Typical use cases

• Blank unused slots during commissioning, protect spare racks in storage or transit, and keep cabinets clean in dusty environments.
