3com TR ユーザーズマニュアル

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.

Refer to this number if you need to report a fault.

Use this connector to attach a Redundant Power 
System (RPS) to the Switch 2000 TR. Disconnect the 
AC plug when using an RPS.

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.

Use the RS-232 console port for connecting a termi-
nal for serial remote or local out-of-band manage-
ment and configuration. Use the following settings to 
configure the VT100:

■

9600 baud

■

8 bit 

■

No parity

■

1 stop bit

Option modules provide alternate downlinks for the 
Switch 2000 TR.

Slide-in modules are available for the following:

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.

ATM is the only computer networking technology 
designed to carry video, voice and data traffic simul-
taneously. ATM provides the level of service necessary
