Before You Begin
Safety and grounding information
Electrical
Hazard
Read the following information before installing or operating
APC
your
Redundant Switch.
• Do not work alone under hazardous conditions.
• Check that the power cord, plugs, and sockets are in
good condition.
• To reduce the risk of electric shock when you can not
verify grounding, d isconnect the R edundant Swi tch from
the power outlet before installing or connecting to other
equipment. Reconnect the power cord only after all
connections are made.
• Do not handle any kind of metallic connector before the
power has be e n removed.
• Use one hand, whenever possible, to connect or
disconnect signal cables to avoid a possible shock from
touching two surfaces with different electrical grounds.
• Connect the equipment to a three-wire
AC
outlet (two
poles plus ground) that is connected t o approp riat e
branch circuit/mains protection (a fuse or circuit
breaker). Connection to any othe r type of r eceptacle may
result in a shock hazard.
• To turn off and disengage the Redundant Switch, press
and hold both
UPS
Off buttons for more than one second
to switch the equipment off, then disconnect the
Redundant Switch from the
AC
power outlet.
• Pluggable equipment includes a protective earth
conductor which carries the leakage current from the
load devices (computer equipment). Total leakage
current must not exceed
3.5
mA.

• The device prevents accidentally tripping of the circuit
breaker, but allows the automatic tripping of the breaker
that protects your equipment when an overload or
malfunction occurs.
• To turn the circuit breaker off when necessary, pull the
left end of the safety device forward so that it no longer
blocks the switch, then push the switch to the OFF
position.
• T o reset a circuit breaker that has tripped automatically:
– Pull the left end of the safety device forward so that it
no longer blocks the switch.
– Let the switch move fully to the left, then push it to the
right.
– Push the left end of the safety device back into place to
block the switch.

Installation
Install management products and the UPS
1. Before you plug in the Redundant Switch and the two
UPS
s, install any compatible
APC
management products:
– If you use a Web/SNMP Management Card, install it
in the card slot of the preferred
APC
Smart-UPS, not in
the card slot of the Redundant Switch.
– Always use the card slot in the Redundant Switch for
APC
any other compatible
management product, such
as the Environmental Monitoring Card.
The Redundant Switch inlets are the main
disconnect devices.

Installation
Attach the brackets to the Redundant Switch
Attach the two included brackets to the Redundant Switch. The
following example shows how to attach the bracket for the
right side. (Attach the left bracket in the same manner.)
1. To allow space to route the cables and to place the
connectors flush with the front of the rack, align the
second hole from the front of the bracket with the first
hole in the side of the Redundant Switch.
2. Insert and tighten the screws that are provided.

Install the rails (4-post rack only)
Mount the rails
if you are using a four-post rack. (In a
only
two-post rack, you mount the Redundant Switch by the
brackets alone.)
For information on which clips and screws your rack requires,
see
Appendix A: Rack-Mount Supplement.

For a four-post rack:
1. Prepare the rack’s rail-holes for mounting the brackets
and rails of the Redundant Switch.
2. Disassem ble each rail by removing the slide screw and
nut !. Set aside the screw, nut, and front segment " of
the rail.
3. Mount the end # of the rear segment of each rail to the
rear rails on the prepared rack, using appropriate rack
hardware.

Troubleshooting
Troubleshooting communications and lost redundancy
With the high availability system, the attached
UPS
s are polled
continuously for capability to carry a load and ability to
communicate with the management software (PowerChute
). When a problem with one of the
plus
UPS
s occurs, power to
the load is not interrupted and polling continues, and
PowerChute
responds by displaying t he m essage, “Self
plus
test failed: invalid test.”
Communications Problems.
If the message “Self test failed:
invalid test.” occurs repeatedly:
1. Check the communications path between the
UPS
s and
the Redundant Switch.
2. Check the front panel of the Redundant Switch.
– If the Status Select
LED
s are flashing in any sequence,
the Redundant Switch has failed. See “Basic
troubleshooting” on page 18.
– If the front panel appears normal, there may be a
