CHAPTER 4: Operation: Hardware and Keyboard Commands

4.3 The Commands in Detail

4.3.1SELECTING A PORT FROM THE SHARED KEYBOARD

To select a port from your keyboard, press and release your keyboard’s left Control key ([Ctrl]), then type in the port number:

If “Maximum Ports” is set to 1 to 9: The ServSwitch will immediately switch to the desired port when you press the one-digit number’s numeral key.

If “Maximum Ports” is set to 10 to 99: The ServSwitch will immediately switch to the desired port when you press the two-digit number’s second numeral key. For single-digit ports, you can enter the number by including a leading zero (“01” for port 1) or by pressing [Enter] after you press the single numeral key. If you press the key of only one digit, and do not follow it with [Enter], the Switch will wait two seconds for you to press [Enter] or another numeral key; then, if no key is pressed, it will switch immediately to the single-digit port.

If “Maximum Ports” is set to 100 to 256: The ServSwitch will immediately switch to the desired port when you press the three-digit number’s third numeral key. For single- and double-digit ports, you can enter the number by including one or two leading zeros (“001” for port 1 or “027” for port 27) or by pressing [Enter] after you press the single or second numeral key. As noted above, the Switch will wait two seconds for you to enter another digit, then will switch to the partially entered port number.

4.3.2SWITCHING TO THE NEXT OR PREVIOUS PORT

From the keyboard you can go forward or backward through the ServSwitch’s ports by selecting either the next or the previous port respectively. To switch to the next port, press and release the left Control key ([Ctrl]), then press the plus key (the key at the top of the keyboard marked with [=] and [+]). To switch to the previous port, press and release [Ctrl], then press the minus key (the key at the top of the keyboard marked with [–] and [_]). The command is not case-sensitive. Do not use the [+] and [–] keys on the keyboard’s numeric pad; the Switch doesn’t recognize these.

You can also select the next or previous port manually from the ServSwitch’s front panel by pushing the button labeled “” or “” respectively (“+” or “–” on the 2-port units). Each time you press the button, the next or previous port in sequence is selected.
