RAM Memory
The SSR 2100’s motherboard uses 64 megabytes of RAM to hold routing and other tables.
To upgrade the amount of memory on the SSR 2100, contact your Cabletron
representative.
Power Supplies
The SSR 2100 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 SSR 2100, 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 SSR
2100 chassis.
Note:
Be sure to plug the SSR 2100 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 SSR 2100 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.
Gigabit Ports
The SSR 2100’s eight Gigabit (1000Base-SX) Ethernet ports are indexed into four groups of
two ports each. The ports connect can operate in full-duplex or half-duplex mode. Each
port can be configured as a switched port or a routed port. The ports have short wave (850
nm) lasers and connect to multimode-mode fiber (MMF) cables.
