cooling within the rack, there must be 7.6 cm (3 in.) of

standard 3 prong power receptacle must be located within

supply requires a positive or negative DC power source at 36-72

volts which is capable of supplying 17 amps.

• The temperature of the location must be maintained between

and 40

2.2 MMAC-M8FNB CONFIGURATION GUIDELINES

The MMAC-M8FNB has eight slots that accept media interface

modules. The slots are numbered from right to left; slot #1 is a

half-width slot that is reserved for a management module. Cabletron

Systems management modules are equipped with a ﬁrmware-based

management tool called Local Management, which lets you control the

MMAC MIMs. Management modules are also SNMP compliant, which

means that an MMAC equipped with a management module can be

managed remotely by SNMP management software (such as any one

of Cabletron Systems’ SPECTRUM

for Open Systems suite of

management products.) The M8PSM-E and -EDC power supply

modules can also be managed remotely using appropriate

management software.

You can combine Token Ring, Ethernet, and FDDI MIMs in the same

MMAC; be sure to consult the appropriate management module and

MIM installation guides for detailed setup information.
