SERVSWITCH™ MULTI

2.5 Safety Precautions

To avoid potential video or keyboard problems with the ServSwitch Multi, take these precautions:

•If the site has 3-phase AC power, make sure that each ServSwitch Multi and all of the computers and monitors attached to it are on the same phase. For best results, they should be on the same circuit.

•Use adapter cables supplied by Black Box only.

To avoid potentially fatal shock and possible damage to equipment, take these precautions as well:

•Do not use 2-wire extension cords with the ServSwitch Multi.

•Test the AC outlets that the monitors and computers are plugged into for proper polarity and grounding.

•Plug the ServSwitch Multi and all monitors and computers into grounded outlets only. If you are plugging the Switch and any attached equipment into a backup power supply (BPS) or uninterruptible power supply (UPS), you should plug the Switch, monitor, and computers into the same supply if at all possible.

•With the exception of adding or removing Cards, you should power down the ServSwitch Multi and all attached computers before you service the unit in any way. Always disconnect the power cord from the unit when you power it down.

Note that the AC inlet is the ServSwitch Multi’s main disconnect.

All ServSwitch Multi models are rated for input voltages of 110 to 240 VAC and input frequency of 50 or 60 Hz. The ServSwitch Multi Hub (KV170RA) is rated for total load-balanced input current of 7 amps: When only one power supply is functioning, it will provide all 7 amps, but when both supplies are working, they will share the load. All other ServSwitch Multi models are rated for 1.6 amps.
