Installation Guidelines

When deciding where to place the RPS 2300, be sure to observe these guidelines:

• Operating environment is within the ranges listed in Appendix A, “Technical Specifications.”
• Airflow around the RPS 2300 and through the vents is unrestricted.
• Clearance to the front and rear panel is such that:

– Front-panel indicators can be easily read.

– Access to ports is sufficient for unrestricted cabling.

– AC power cord can reach from the AC power outlet to the power supply modules on the RPS 2300 front panel.

• Cabling is away from sources of electrical noise, such as radios, power lines, and fluorescent lighting fixtures. Make sure the cabling is safely away from other devices that might damage the cables.

To provide enough distance for cabling, place switches and routers using the RPS 2300 close to the RPS. The maximum RPS cable length is 1.5 meters.

• If only one power supply is installed in the RPS 2300, the spare power supply insert that ships with RPS 2300 must be installed in the empty power supply slot.
• When installing the RPS 2300 is a rack with a switch stack, install the
  RPS 2300 at the bottom of the rack. If needed, allow one RU space between the RPS 2300 and the first switch above to provide room for cabling. Connect the RPS cable to the switch before connecting any StackWise cables.

For information about installing the RPS with the switch see the Catalyst 3750-E and Catalyst 3560-E Hardware Installation Guide.

• Make sure that any power supply module or fan module is securely fastened in the RPS 2300 front panel.

Warning

To prevent bodily injury when mounting or servicing this unit in a rack, you must take special precautions to ensure that the system remains stable. The following guidelines are provided to ensure your safety: This unit should be mounted at the bottom of the rack if it is the only unit in the rack. When mounting this unit in a partially filled rack, load the rack from the bottom to the top with the heaviest component at the bottom of the rack. If the rack is provided with stabilizing devices, install the stabilizers before mounting or servicing the unit in the rack.

To install the RPS 2300 in a rack, you must first remove the screws from the RPS chassis so that the mounting brackets can be attached. For attachment at the front-mounting position, remove three Phillips truss-head screws from the RPS 2300 side panels (Figure 2-1). For attachment at the mid-mounting position, remove one screw. For attachment at the rear-mounting position, remove two screws.

Figure 2-1 Removing Screws from the RPS 2300

Figure 2-2 shows how to attach a bracket to one side of the RPS 2300 for installation into a 19-inch rack with the front panel or rear panel of the RPS 2300 facing forward.

Figure 2-2 Attaching Brackets for 19-Inch Racks

Mounting the RPS 2300 in a Rack

After you attach the brackets to the RPS 2300, use the four supplied number-12 Phillips machine screws to securely attach the brackets to the rack (Figure 2-3). Use the black Phillips machine screws to attach the cable guide to the left or right bracket.

Note If you are installing the RPS 2300 in a rack with a switch stack, install the RPS 2300 at the bottom of the rack. If necessary, allow one RU space between the RPS 2300 and the switch above to provide room for cabling.

Cabling Options

The switches have different cabling options that you use to connect to the
RPS 2300. The RPS 2300 uses these connector cables:

• RPS cable for the Catalyst 3750-E and 3560-E switches (CAB-RPS-2300-E=): 22-pin connector on one end and 22-pin connector on the other end.
• RPS cable (CAB-RPS-2300=): 22-pin connector on one end and 14-pin connector on the other end. Use this cable to connect the RPS 2300 to all other supported Cisco devices.

For a complete list of products that the RPS 2300 supports, see the Cisco Redundant Power System 2300 Compatibility Matrix available on Cisco.com.

For more information about the RPS cables, see Appendix B, “Connector and Cable Specifications.”

Power Considerations

The switch connected to the RPS 2300 might restart when it changes from RPS power to its internal power. We recommend that you first divert switch traffic to an alternate switch to avoid data loss. This does not occur on the Catalyst 3750-E or Catalyst 3560-E switches.

Connecting the Cables

This section describes how to connect the cable and power supply modules to the RPS 2300.

(Optional) The RPS is shipped with a single ground lug for grounding the
RPS 2300. Use the ground screw to attach the single ground lug and wire assembly to the RPS 2300 rear panel. Torque the ground lug screw to 60 lbf-in. (960 ozf-in.).

Note In installations that require Network Equipment Building Systems (NEBS)-compliant grounding, use 10-AWG (6 mm2) copper wire.

Note If you are connecting another device to the RPS 2300, place the RPS port to be connected into standby mode. This prevents the device that the RPS 2300 is backing up from losing power.

Follow these steps to connect the cables:

Step 1 Connect the power cable to the power supply (Figure 2-7), and connect the other end of the power cable to an AC-power source.

Step 2 Connect one end of the RPS cable to an RPS DC output connector (Figure 2-6).

Step 3 Connect the other end of the RPS cable to the RPS receptacle on the switch.

Step 4 Repeat through Step 3 for each switch that the RPS 2300 supports.

Step 5 Using a ratcheting torque screwdriver, torque each screw to 5 in-lbf. (80 ozf-in.).

To ensure proper operation, be sure that you completely seat the connector and that you securely tighten the screws.

Step 6 (Optional) Press the RPS Standby/Active button to put the RPS 2300 into active mode.

Step 7 The RPS LEDs and DC-output LEDs for the connected devices should be green. If they are not green, see Chapter1, “Troubleshooting”

Note To power off the RPS 2300, disconnect the AC-input power from the RPS 2300, and disconnect all connected DC port connector cables.
