ii APC Redundant Switch: Installation and Operation Manual
Before You Begin Safety and grounding information Electrical Hazard Read the following information before installing or operating your APC 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, disconnect the Redundant Switch from the power outlet before installing or connecting to other equipment.
Pre-Installation Procedures Receiving inspection Inspect the package and contents for shipping damage, and make sure that all parts were sent. Report any damage immediately to the shipping agent, and report missing contents, damage, or other problems immediately to APC or your APC reseller. Please recycle The shipping materials are recyclable. Please save them for later use, or dispose of them appropriately.

Installation Install management products and the UPS 1. Before you plug in the Redundant Switch and the two UPSs, 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 any other compatible APC management product, such as the Environmental Monitoring Card.
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.
Installation Install the rails (4-post rack only) Mount the rails only if you are using a four-post rack. (In a 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. Disassemble each rail by removing the slide screw and nut !.
Installation 4. On each side, attach the front rail segment that you set aside in step 2 to the Redundant Switch. a. Align the top two holes on the front rail segment with the two holes on the side (toward the rear) of the Redundant Switch. b. Attach the rail segment with the tapered-head screws provided.
Installation Connect and route the cables 1. To the front of the Redundant Switch, connect the communications cable and any accessory cables that require front connections. 2. Route the cables around the Redundant Switch through the side channel (marked with arrows below) to the equipment in the rack. Redundant Switch 3. Optionally, install a plastic twist-lock (provided) on each side to secure the cables.
Installation Mount the Redundant Switch in the rack Use two people to lift the Redundant Switch. Heavy 1. Slide the front rail segments attached to the Redundant Switch into the rear rail segments attached to the rack. 2. From the rear of the rack, insert and tighten the slide screws and nuts. Connect your equipment Do not connect laser printers through the Redundant Switch Caution 1. Use your server’s power cords to connect to the Redundant Switch. 2.
Installation Turn on the equipment and Redundant Switch Connect the PowerChute® cable 1. Turn on all connected equipment. 2. To provide power to the equipment, press the ON button of UPS-A to turn on the Redundant Switch and UPS-B. 3. To test whether the cables are connected correctly, press the OFF button on one UPS. – If it turns back on, the cabling is correct. – If it does not turn back on, try swapping the two UPS communications cables to correct the problem.
Configuration Supported configurations Two supported configurations for Redundant Switch are shown below. For more information on these and other supported configurations, visit the APC Web site at www.apc.com. Install only SNMP accessories in the UPS. You must install any other accessories in the Redundant Switch Note Both UPSs must be the same sine-wave model. Minimum acceptable configuration: Redundant Switch with two Smart-UPS units connected to one AC line (the same facility power source).
Configuration b. Restart the computer on which PowerChute plus is installed. c. Start PowerChute plus. Communication is to UPS-A. d. Configure UPS-A according to your requirements. e. Set the UPSID to UPS_A. When one UPS becomes unavailable When one of the two UPSs becomes unavailable to supply AC power, PowerChute plus sends the message “Self test failed: invalid test.” Any of the following conditions will cause the message to occur: • A UPS self-test fails.
Operation Controls, LEDs, and ports on the front panel Redundant Switch Storage APC recommends the factory default settings among the settings shown below.
Operation Emergency Power Off You can use a remotely operated Emergency Power Off (EPO) switch to turn off the UPS and disconnect power to the equipment load. When you turn off the UPS through the Emergency Power Off system, it will turn off immediately without switching to battery operation. Electrical Hazard Use only a licensed electrician to perform the following procedure to connect the Redundant Switch and its attached UPSs to your Emergency Power Off system. 1. Use the EPO connector. 2.
Operation Front panel programmable settings The following programmable settings are accessible using controls located on the Redundant Switch front panel. Function Select LED Indicator. The three green Function Select LEDs indicate which user programmable parameter is selected for status display or modification. Use the left selection button to cycle through the five configurable items defined in “Controls, LEDs, and ports on the front panel” on page 15. Function Status LED Indicator.
Troubleshooting Basic troubleshooting Electrical Hazard Only trained APC technicians should open the Redundant Switch for repair. Problem Possible Cause Corrective Actions Very low utility voltage, or no utility voltage. Use a lamp with an incandescent bulb to test the AC power supply to the Redundant Switch. If the bulb lights very dimly or not at all, have the utility voltage checked. Ensure that the AC cables are properly connected between the Redundant Switch and the UPSs.
Troubleshooting Troubleshooting communications and lost redundancy With the high availability system, the attached UPSs are polled continuously for capability to carry a load and ability to communicate with the management software (PowerChute plus). When a problem with one of the UPSs occurs, power to the load is not interrupted and polling continues, and PowerChute plus responds by displaying the message, “Self test failed: invalid test.” Communications Problems.
