GM4-B12M

Description

12-slot main base for GLOFA GM4; maximum single-chassis local capacity; not expandable.

The Polar Energy Assessment:

The GM4-B12M provides the largest single-rack capacity in the GM4 lineup: CPU, local power and up to 12 modules on one backplane. OEM manuals note the 12-slot main is not expandable, so plan slot allocation carefully. Use this when you want maximum consolidation of modules into a single cabinet, bearing in mind power and thermal constraints.

Pros

• Highest single-rack slot capacity for consolidated designs.
• Reduces inter-rack cabling compared with multiple small racks.

Limitations

• Not expandable beyond 12 slots; future growth requires architecture changes.
• Higher heat and power concentration requires planning.

Typical use cases

• Central control racks for medium plants, OEM cabinets wanting maximum local I/O, and retrofit scenarios where consolidation cuts cabling work.
