The following are additional items needed to use your DSR1021 switch:

•DSR software

•V.34, V.90 or V.92-compatible modem and cables (for optional modem connection)

Verification of Internet/server connections

DSR switch

The front panel of the DSR1021 switch features two LEDs indicating the Ethernet connection. The top green LED is the Link indicator. It will illuminate when a valid connection to the network is established and blink when there is activity on the port. The lower amber LED, labeled 100M, will indicate that you are communicating at the 100 Mb rate when using an Ethernet connection.

Additionally, there are two LEDs above each port number on the front of your DSR1021 switch: one green and one amber. The green LED will illuminate when the attached system is powered. The amber LED will illuminate when that port is selected.

DSRIQ modules

PS/2, Sun and USB DSRIQ modules are available for attaching computers to your DSR switch.

The DSRIQ-SRL serial module is used to connect serial devices to your DSR switch and features two green LEDs: a POWER LED and a STATUS LED. The POWER LED indicates that the attached server is powered. The STATUS LED indicates that a valid UTP connection has been made to a DSR switch. The DSRIQ-SRL module prevents a serial break from the attached device if the module loses power. However, a user can generate a serial break with the attached device by pressing Alt-Bin the Terminal Applications menu.
