Installing the Power Enclosure, Power Trays, and Exterior Cosmetics

This chapter provides instructions on installing the Cisco NCS 6000 Fabric Card Chassis power enclosure, power trays, and exterior cosmetics.

About the Power Enclosure

The Cisco NCS 6000 FCC ships with a separate empty power enclosure (Cisco PID NCS-F-PWR-SHELF). The power enclosure consists of one power shelf, four slots for AC or DC power trays, and two power control modules (PCMs).

The upper two power trays (PT0 and PT1) are referred to as power shelf 0 (PS0), and the lower two power trays (PT2 and PT3) are referred to as power shelf 1 (PS1) Figure 3. Each set of power trays has a power control module (PCM) with its own I/O power switch. Three AC power modules or four DC power modules can be installed in each power tray. See the Installing an AC or DC Power Module section.


Note
Usually, it is not necessary to remove the power enclosure although it is field-serviceable. For information about removing the power enclosure components, see the Replacing an AC or DC Power Tray section.

Installing the Power Enclosure

This section describes how to install the power enclosure in the Cisco NCS 6000 FCC.

Required Tools and Equipment

  • 6-inch, Number-2 Phillips screwdriver

  • Power enclosure (Cisco PID NCS-F-PWR-SHELF)


Note
The power enclosure weighs approximately 30 pounds and sits on top of the FCC. To prevent injury, we recommend that you use a ladder and use two people when installing the power shelf.

Steps

Follow these steps to attach the power enclosure to the FCC:

    Step 1   Lift and place the power enclosure (busbar facing back) at the top of the FCC.
    Caution    Handle the power shelf by lifting it at the sides and along the bottom of the shelf when installing it into the FCC. Avoid lifting the shelf from the center bottom.

    Step 2   Position and align the two rails on each side of the underside of the power enclosure with the two rails at the top of the FCC. When the shelf is aligned properly, it will easily slide in place.
    Step 3   Slowly push the power enclosure forward until the front flange with the three captive screws engages with the front of the FCC.
    Step 4   Loosely tighten the captive screws (two per side) on the power enclosure, and then loosely tighten the three captive screws on the front flange.
    Step 5   Repeat Step 4, tightening all captive screws to firmly attach the power enclosure to the FCC.
    Step 6   Attach the two D-Sub connector cables to the two PCM connectors on back of the power enclosure and tighten the captive screws on each cable connector. The individual PCMs are labeled PCM0 and PCM1.
    Step 7   Tighten the captive screws on each cable connector.

    Installing the Power Trays

    This section describes how to install an AC or DC power tray in the power enclosure and includes the following topics:


    Note
    Although there are differences between AC and DC power trays, they are installed by using the same procedures described in this section. Once they are installed into an FCC that is properly grounded, external grounding to the power tray is not needed.

    About the AC and DC Power Trays

    The Cisco NCS 6000 FCC power enclosure supports either four AC power trays or four DC power trays. An AC power tray houses up to three AC power modules, while a DC power tray houses up to four DC power modules. See the Installing an AC or DC Power Module section.


    Note
    Only one type of power tray can be installed in the power enclosure. You cannot mix AC and DC power trays.

    Note
    For a DC power tray, the rear input LED starts to light up when the input voltage reaches -20 VDC, gets brighter as the voltage increases, and is fully lit when the input voltage reaches -48 VDC.

    Installing an AC or DC Power Tray

    This section describes how to install an AC or DC power tray in the Cisco NCS 6000 FCC.


    Note
    For information about removing a power tray, see the Replacing an AC or DC Power Tray section.

    Prerequisites

    Before you install an AC or DC power tray, do the following:

    • Remove the top grilles from both the front and rear sides of the FCC, if installed.
    • Ensure the power tray you are about to install is empty. Do not install a power tray into the FCC with the PMs installed in the power tray.

    Required Tools and Equipment

    • Four M4 x 10 mm screws per power tray

    • 6-inch, Number-2 Phillips screwdriver

    • Number-2 Phillips torque screwdriver with torque rated up to 55 in-lb (6.2 N-m)

    • AC or DC power tray

      • AC power tray (Cisco PID NCS-AC-PWRTRAY)

      • DC power tray (Cisco PID NCS-DC-PWRTRAY)

    Steps

    To install an AC or DC power tray, follow these steps:

      Step 1   Using two people, one to support the power tray underneath and the other to keep it steady, lift the power tray up and slide it partially into a power tray slot on the power enclosure.
      Caution    Because of the weight of a power tray, 20 lb (9 kg), and the height at which a power tray is installed in the FCC, be especially careful while removing and carrying a power tray. To prevent injury, avoid sudden twists or lateral moves.
      Step 2   Grasping both handles simultaneously, push both the left and right handles in at the same time to push the tray into the power enclosure. Slide the tray all the way into the enclosure until both power tray handles engage the slots.
      Caution    Use care not to bend the handles.
      Figure 7. Installing a Power Tray into the Power Enclosure—DC Power Tray Shown

      Step 3   Use the screwdriver to loosely tighten the four M4 x 10 mm screws that attach the power tray to the power enclosure.
      Step 4   Use the torque screwdriver to tighten the four screws to a torque value of 15 in-lb (1.69 N-m) to 20 in-lb (2.26 N-m).
      Note    The screws that attach a power tray to the power shelf are relied upon for power tray bonding and grounding.
