Safety This section contains important instructions that should be followed during installation and maintenance of the Redundant Switch. It is intended for customers who setup, install, relocate, or maintain APC equipment. Electrical Safety • Do not work alone under hazardous conditions. • High short circuit current through conductive materials could cause severe burns. • Check that the power cord(s), plug(s), and sockets are in good condition.
Initial Startup Reminder! To obtain warranty coverage, please fill out and return the warranty registration card now. Inspection Inspect the Redundant Switch upon receipt. Notify the carrier and dealer if there is damage. The packaging is recyclable; save it for reuse or dispose of it properly. Unpacking The Redundant Switch package contains the Redundant Switch unit, its bag of hardware (OM8500), 1U mounting rails, and its bag of mounting hardware (OM-7600).
1. Install Redundant Switch. •Before plugging in the unit, install any compatible SmartSlot accessory (check our website at www.apcc.com). Follow the installation instructions that come with the accessory. Notes: 1. This Redundant Switch is equipped with a SmartSlot for additional manageability. See the APC Website (www.apcc.com) for information on plug-in accessories. 2. SNMP accessories are currently unsupported in the Redundant Switch SmartSlot.
Install the Rails Note: The mounting rails are only necessary if you are using a four-post rack. If you are using a two-post rack the Redundant Switch will be mounted by the ears alone. Skip to Connect and Route the Cables. Two rails and associated hardware are included with the Redundant Switch. For information on which clips and screws the rack you are using requires, see Appendix A: Rack Mount Supplement. Prepare the rack’s rail-holes to mount the Redundant Switch’s ears and rails as appropriate.
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.
