Unpacking and Mounting the RPS

 

Unpacking an EX Series Redundant Power System

The Redundant Power System (RPS) is shipped in a cardboard carton, secured with foam packing material. The carton also contains an accessory box. A separate cardboard carton contains one EX-PWR3-930-AC power supply.

Note

The RPS is maximally protected inside the shipping carton. Do not unpack it until you are ready to begin installation.

To unpack an RPS:

  1. Move the shipping carton to a staging area as close to the installation site as possible, but where you have enough room to remove the RPS.
  2. Position the carton so that the arrows are pointing up.
  3. Open the top flaps on the shipping carton.
  4. Remove the accessory box and verify the contents against the parts inventory on the label attached to the carton.
  5. Pull out the packing material holding the RPS in place.
  6. Verify the components received against the packing list included with the RPS. An inventory of parts supplied with the RPS is provided in Parts Inventory (Packing List) for an EX Series Redundant Power System.
  7. Save the shipping carton and packing materials in case you need to move or ship the RPS later.

Parts Inventory (Packing List) for an EX Series Redundant Power System

Note

The RPS ships with one power supply in a separate box. Additional EX-PWR3-930-AC power supplies for RPS must be ordered separately.

Mounting the EX Series Redundant Power System

You can mount the Redundant Power System (RPS) on a 19-in. equipment rack or cabinet by using mounting brackets. The RPS is shipped with mounting brackets and mounting screws to be used to secure the mounting brackets to the RPS chassis.

The RPS is shipped with one pair of mounting brackets. The holes in the mounting brackets are spaced at 1 U (1.75 in. or 4.445 cm), so that the RPS can be mounted in any rack that provides holes spaced at that distance.

The outer edges of the mounting brackets extend the width of the RPS to 19 in. (48.2 cm) and the front of the chassis extends approximately 0.5 in. (1.27 cm) beyond the mounting brackets when the RPS is front-mount on a rack.

You can mount an RPS:

  • On two posts in a 19-in. rack or cabinet by using the mounting brackets provided with the RPS.

  • On four posts in a 19-in. rack or cabinet by using the separately orderable four-post rack-mount kit.

  • In a position recessed 2 in. from the front of a 19-in. rack or cabinet by using the 2-in. recess front brackets in the separately orderable four-post rack-mount kit. You can mount the RPS in this recessed position on two-post or four-post racks and cabinets.

Mounting an EX Series Redundant Power System in a Recessed Position in a Rack or Cabinet

You can mount a Redundant Power System (RPS) in a rack or cabinet such that the RPS is recessed inside the rack from the rack front by 2 inches. You can use the 2-in.-recess front brackets provided in the separately orderable four-post rack-mount kit to mount the RPS in a recessed position.

You might want to mount the RPS in a recessed position in a cabinet if the cabinet doors do not close completely unless the RPS is recessed.

To mount the RPS in a recessed position on two posts, follow the instructions in Mounting an EX Series Redundant Power System on Two Posts in a Rack or Cabinet. To mount the RPS in a recessed position on four posts, follow the instructions in Mounting an EX Series Redundant Power System on Four Posts in a Rack or Cabinet.

Mounting an EX Series Redundant Power System on Four Posts in a Rack or Cabinet

You can mount a Redundant Power System (RPS) on four posts of a 19-in. rack or cabinet by using the separately orderable four-post rack-mount kit. (The remainder of this topic uses “rack” to mean “rack or cabinet.”)

Note

You can position either the switch connector side or the power supply side of the RPS at the front of the rack.

Before mounting the RPS on four posts in a rack:

Ensure that you have the following parts and tools available:

  • Phillips (+) screwdriver, number 2

  • 6 flat-head 4-40 mounting screws (provided with the four-post rack-mount kit)

  • 12 flat-head 4x6-mm Phillips mounting screws (provided with the four-post rack-mount kit)

  • One pair each of flush or 2-inch-recess front brackets

  • One pair of side-rail brackets

  • One pair of rear brackets

  • Screws to secure the chassis and the rear brackets to the rack (not provided)

Note

We recommend that you first mount the RPS and then install the power supplies in it.

Caution

If you are mounting multiple RPSs on a rack, mount the heaviest RPS at the bottom of the rack and mount the other RPSs from the bottom of the rack to the top in decreasing order of the weight of the units.

To mount the RPS on four posts in a rack:

  1. Attach the front brackets (either the flush or the 2-inch-recess brackets) to the side-rail brackets using the six 4-40 flat-head Phillips mounting screws. See Figure 1.
    Figure 1: Attaching the Front Bracket to the Side-Rail Bracket
