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 Ser vSwitch Multi.
• Test the AC outlets that the monitors and computers are plugged into for proper polarity and grounding.
• Plug the Ser vSwitch 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 Ser vSwitch 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.
2.6 The System and Its Components

• Each Ser vSwitch Multi Base Unit (KV150A-R2) and ServSwitch Multi MX (KV155A) is shipped from the
factory with an embedded local-console module, a power cord, and a copy of this manual.
• Each Ser vSwitch Multi EXP (Expansion Chassis, KV160A-R2) and ServSwitch Multi SB (KV162RA) comes
from the factory with a power cord and a copy of this manual.
• Each Ser vSwitch Multi Hub (KV170RA) comes from the factory with its two power-supply modules and two

If you didn’t receive everything, or if anything arrived damaged, call Black Box right away.
In addition, you’ll need other components to build a complete ServSwitch Multi system (contact Black Box
Technical Support if you’re not sure what you’ll need for your application). With the Base Unit, MX, EXP, or
SB, you’ll need some combination of:
• One or more Autosensing CPU-Inter face Cards (KV2000C) and one or more 8-foot (2.4-m), 20-foot
(6.1-m), or 30-foot (9.1-m) CPU (Server) Cables to attach servers or other computers to the Switch.
