Mount the Redundant Switch in the Rack
Note:
Two people should perform this step.
1. Position the Redundant Switch forward of the mounted rear rail segments.
2. Align the front and rear rail segments and slide the front segment onto the rear segment.
3. Align the Redundant Switch ears with the front rack rails and use rack hardware to secure the
mounting ears to the rack rails.
4. From the rear of the rack, insert and tighten the slide screws and nuts.
2. Connect Equipment.
• Do not power laser printers through the Redundant Switch.
• Use your server’s power cords to connect to the Redundant Switch.
• Install the 940-1000A communication cable(s) between each UPS and the Redundant Switch. Make
sure that the communications cable for the preferred UPS, UPS-A, and the power cord for
UPS-A are connected to the same UPS.
Note:
If you have more loads to connect than there are outlets provided, use a power strip.
Visit APC's Website (www.apcc.com) for rack mountable multiple outlet solutions.
3. Turn on Redundant Switch.
• Turn on all connected equipment.
• Press the ON switch of UPS-A to turn on your Redundant Switch and UPS-B. This will power-up
connected equipment.
Note:
To test whether the cabling is correct, shut off one UPS using its OFF button. If it turns back on,
the cabling is correct. If not, swap the two UPS communication cables.
4. Connect PowerChute Cable.
• When you are ready to install PowerChute® plus, install the PowerChute® plus communication
cable between the Redundant Switch’s server port and the server’s serial port.
Note:
When managed by PowerChute® plus UPS software, the Redundant Switch should be used with
servers running Windows NT, Solaris, or Netware.
