Power Socket
The Switch 2000 TR automatically adjusts to the
supply voltage. The fuse is suitable for both 110 AC
and 220-240 AC operation. Refer to “Replacing the
Fuse in Chapter 2 for information on replacing fuses.
NOTE: The Switch 2000 TR has no ON/OFF switch.
Serial Number
Refer to this number if you need to report a fault.
Redundant Power System Connector
Use this connector to attach a Redundant Power
System (RPS) to the Switch 2000 TR. Disconnect the
AC plug when using an RPS.
Reset Button
Using the Reset button simulates a power on/off
cycle. You can also perform a software reset using the
VT100 interface. Refer to “Setting Up the VT100
Console in Chapter 3.

Slide-in modules are available for the following:
The ATM Module
The SuperStack II Switch TR ATM OC-3 module pro-
vides a high-speed ATM connection between the
Switch 2000 TR and ATM networks. When positioned
in workgroup or departmental LANs, the ATM down-
link module offers a 155 Mbps data path to building,
campus or ATM network backbones directly from the
Switch 2000 TR. Perfect for providing cost-effective
ATM access to smaller isolated LANs or bandwidth
intensive and mission critical applications, the ATM
downlink also provides a logical migration path for
existing Token Ring LANs to mainstream high-speed
networking technologies.
Redundant links can protect your Switch 2000 TR
from network failure or equipment inconsistencies.
The built-in Software Upgrade feature allows you to
download software revisions easily.
Benefits of an ATM
ATM is the only computer networking technology
designed to carry video, voice and data traffic simul-
taneously. ATM provides the level of service necessary
