Install the PTX12008

This topic guides you through the steps to install the PTX12008 in a 19-inch wide four-post rack or in a cabinet that has a 19-inch wide four-post rack.

You can install the PTX12008 in a 19-inch wide four-post rack or in a cabinet that has a 19-inch wide four-post rack. The remainder of this topic uses rack to mean rack or cabinet.

Complete these prerequisites before you install the router:

  • Prepare the site for installation as described in Site and Electrical Guidelines.

  • Ensure that the site has adequate clearance for both airflow and hardware maintenance.

    Figure 1: Clearance Requirements for PTX12008 Technical diagram of a rectangular object requiring 24-inch clearances with dimensions labeled in inches and centimeters.

  • Unpack the router as described in Unpack the PTX12008.

CAUTION:

Before mounting the router, a qualified technician must verify that the rack is strong enough to support the router's weight. Have the technician also verify that the rack has adequate support at the installation site.

If you are installing more than one router on a rack, install the first router at the bottom of the rack.
CAUTION:

Do not install Flexible PIC Concentrators (FPCs) in the chassis until after you mount the chassis securely on a rack.

Install the PTX12008 in a Rack by Using the PTX12K-RMK Rack Mount Kit

You can install the PTX12008 in a 19-inch wide four-post rack or in a cabinet that has a 19-inch wide four-post rack by using the PTX12K-RMK rack mount kit or by using the PTX12K-RMK-EXT rack mount kit intended for heavy-duty use. This topic explains the procedure to install the PTX12008 by using the PTX12K-RMK rack mount kit. The remainder of this topic uses rack to mean rack or cabinet.

The PTX12K-RMK rack mount kit is provided by default. The PTX12K-RMK-EXT rack mount kit is separately orderable.

Before you install the PTX12008 in a rack, review the following:

To install the PTX12008 in a rack:

  1. Wrap and fasten one end of the ESD grounding strap around your bare wrist, and connect the other end to a site ESD point.
  2. On the front of each front rack post, insert a screw appropriate for your rack in the screw slot in the center of a rack unit, partially. Rest the bottom slot of the mounting tray on the screws. The mounting tray extends toward the center of the rack. Tighten the screws by using a screwdriver.

  3. Attach the mounting tray to the front rack posts by using six screws appropriate for your rack and a screwdriver.
    Assembly instructions for metal shelf with vertical supports and adjustable shelves. Dashed lines show screw placement.
  4. From the rear of the rack, slide the mounting tray brackets into the grooves of the mounting tray. Attach the mounting tray brackets to the rear rack posts by using four rack-mounting screws each appropriate for your rack and a screwdriver.
    Assembly diagram of metal shelving with vertical supports and horizontal beams, showing bolt attachment and assembly direction.
  5. Ensure that the mounting tray is level by verifying that all the screws on one side of the rack align with the screws on the other side of the rack.
  6. Attach the mounting tray brackets to the mounting tray with a minimum of 16 Phillips M4x8mm flat-head screws. Tighten the screws using a Phillips (+) screwdriver, number 2. Apply 18 lb⋅in (2 Nm) of torque to the screws. You can install up to 18 screws on each side. We recommend that you install as many screws as possible.

    Note: The router weighs 275 lb (124.7 kg) without any FRU installed. Because of the router's size and weight, we strongly recommend that you use a mechanical lift to mount the router.
  8. Load the router onto a lift, making sure it rests securely on the lift platform.
  9. Using the lift, align the chassis in front of the rack and center it in front of the mounting tray.

  10. Lift the chassis slightly above the surface of the mounting tray. Position the chassis as close as possible to the mounting tray.
  11. Carefully slide the chassis onto the mounting tray until the chassis flanges contact the rack posts. We recommend that at least two people push the router onto the mounting tray while a third person aligns the router to the mounting tray.
  12. Move the lift away from the rack.
  13. Check the alignment of the router. The rack-mounting screw slots on each side of the rack should line up, and the router should be level.
  14. Attach the two chassis flanges to the front posts of the rack by using rack-mounting screws appropriate for your rack and a screwdriver. You must use nine rack-mounting screws for each chassis flange.

  15. Attach the two rear side brackets to the rack by using rack-mounting screws appropriate for your rack and a screwdriver. You must use eight rack-mounting screws for each mounting bracket. Depending on the location of the rack posts in relation to the chassis, you can attach the rear side brackets in two different orientations. Figure 2 shows the orientation of the brackets when the chassis extends out of the rack posts. Figure 3 shows the orientation of the brackets when the chassis is inside the rack posts.

  16. Attach the chassis to each rear side brackets by installing eight Phillips M4x8mm pan head screws through each open flange hole and a screw slot on the rack. Tighten the screws using a Phillips (+) screwdriver, number 2. Apply 18 lb⋅in (2 Nm) of torque to the screws. Depending on the location of the rack posts in relation to the chassis, you can use the rear brackets in two different orientations. Figure 4 shows the orientation of the brackets when the chassis extends out of the rack posts. Figure 5 shows the orientation of the brackets when the chassis is inside the rack posts.

Install the Front Door

The front door protects fiber-optic cabling and provides additional protection from electromagnetic interference (EMI).

Before you install the PTX12008 in a rack, review the following:

  • Ensure that you understand how to prevent electrostatic discharge (ESD) damage. See Prevention of Electrostatic Discharge Damage.

  • Ensure that you have the following parts and tools available:

    • An ESD grounding strap—not provided

    • A Phillips (+) screwdriver, number 2—not provided

To install the front door on a PTX12008:

  1. The front door comes in three pieces. Assemble the front door. Attach the side panels of the front door to the front panel of the front door by inserting the five thumb screws located on each side panel into the front panel. Tighten the screws.
