Ram Memory; Power Supplies; Fans - Cabletron Systems IA1100 Getting Started Manual

RAM Memory

The IA 1100/1200's motherboard uses 64 megabytes of RAM to hold routing and other
tables. To upgrade the amount of memory on the IA 1100/1200, contact your Cabletron
representative.

Power Supplies

The IA 1100/1200 uses two power supplies, each delivering 3.3, 5, and 12 volts DC to the
motherboard, internal fans, and other components. Each power supply provides a portion
of the power necessary to operate the IA 1100/1200, with the added feature that, in the
unlikely event that one of the power supplies should fail, the remaining power supply
will assume the entire load and provide enough current to operate a fully configured IA
1100/1200 chassis.
Note:
Be sure to plug the IA 1100/1200 into a single-phase grounded power source
located within 6 feet of the installation site.
The following table lists the specifications for the power supplies.

Fans

The IA 1100/1200 contains three internal fans to provide cooling air flow across the
motherboard and Gigabit ports. The fans are located near the middle of the chassis,
between the power supplies and the motherboard.
Note:
To ensure that the fans can provide adequate cooling, Cabletron recommends that
you allow a minimum of 3 inches of clearance on each side of the chassis.
