SERVSWITCH™ WIZARD EXTENDER

5. Operation

This chapter explains the general operation of the ServSwitch™ Wizard Extender. We recommend that you read this chapter carefully before starting to use the Extender; also make very sure you have read the important note at the start of Chapter 4!

5.1 Power-Up Status

Under normal circumstances, the ServSwitch Wizard Extender is ready for use as soon as the transmitter and receiver power up. The receiver will draw power from its power adapter or from the optional power supply; the transmitter will draw power from the attached CPU’s keyboard port. If either module’s LED remains dark when the module should be operating, the module isn’t receiving enough power to do so.

How the receiver behaves at bootup when both modules are properly powered will depend on how position 3 of the transmitter’s DIP switch is set (see Section 4.2.1) and on whether you’ve set a password for the Extender or not (see

Section 4.4):

•If position 3 is set to ON, the Extender will go directly into configuration mode (see Section 4.2.2), so that you can reconfigure it as necessary before pressing [Enter] to resume normal operation. (This is most commonly done to clear an incorrectly entered or forgotten password—see Section 4.4.)

•If position 3 is set to OFF but you haven’t set a password, the receiver will establish a connection to the transmitter and will light its LED.

•If position 3 is set to OFF and you have set a password, the receiver will light its LED but will not display any video. It will show that it’s expecting you to enter the password by alternately flashing the Num Lock/Scroll Lock LED pair and the Caps Lock LED on the attached keyboard. When you type in the password at the keyboard and press [Enter], the receiver will “unlock,” stop flashing the keyboard LEDs, and then establish a connection to the transmitter.
