Installing the PTX5000 in a Rack

Installing the PTX5000 Mounting Hardware for a Four-Post Rack or Cabinet

Installing Cage Nuts, If Needed

Insert cage nuts, if needed, into the holes listed in Table 1 and Table 2 (an X indicates a mounting hole location). The hole distances are relative to the standard U division on the rack that is aligned with the bottom of the mounting shelf and rear support bracket.

To install cage nuts in a four-post rack:

  1. On the rear rack rails, insert cage nuts in the holes specified for the rear support bracket. Install the cage nuts in the rear of the rear rail (see Table 1).
  2. On the front rack rails, insert cage nuts in the holes specified for the four-post mounting shelf. Install the cage nuts in the front of the front rail (see Table 1).
  3. On the front rack rails, insert cage nuts in the holes specified for mounting the chassis. Install the cage nuts in the front of the front rail (see Table 2).

Installing the Four-Post Mounting Shelf and Rear Support Bracket

To install the four-post mounting shelf and rear support bracket (see Figure 1):

  1. On the rear of each rear rack rail, partially insert a mounting screw into the lowest hole specified in Table 1.
  2. Install the rear support bracket on the rear of the rear rack rails. Rest the bottom slot of the rear support bracket on a mounting screw. The rear support bracket extends toward the center of the rack.
  3. Partially insert screws into the open holes in the rear support bracket.
  4. Tighten all the screws completely.
  5. On the front of each front rack rail, partially insert a mounting screw into the lowest hole specified in Table 1.
  6. Install the four-post rack mounting shelf on the front rack rails. Rest the bottom slot of the front flange on a mounting screw. Rest the back of the four-post rack mounting shelf on top of the rear support bracket.
  7. Partially insert screws into the open holes in the mounting shelf.
  8. Tighten all the screws completely.
  9. Fasten the four-post mounting shelf to the rear support bracket by partially inserting the screws provided in the accessory kit into the open holes on top of the four-post mounting shelf.
    Note:

    Several holes are provided on top of the shelf. Two holes on each side of the shelf will align with the holes in the rear support bracket.

  10. Tighten all the screws completely.

Removing the Center-Mounting Brackets

The center-mounting brackets are not used for a four-post rack, and must be removed from the chassis.

To remove the center-mounting brackets from the chassis:

  1. Loosen the screws from each bracket (see Figure 2).
  2. Remove each bracket.

Installing Cage Nuts, If Needed

Insert cage nuts, if needed, into the holes listed in Table 3 and Table 4. The hole distances are relative to the standard U division on the rack that is aligned with the bottom of the mounting shelf and rear support bracket.

To install cage nuts in an open-frame rack:

  1. On the rear side of both rack rails, insert cage nuts in the holes specified for the open-frame mounting shelf (see Table 3).
  2. On the front side of both rack rails, insert cage nuts in the holes specified for mounting the chassis (see Table 4).

Installing the Open-Frame Rack Mounting Shelf

Before mounting the chassis in an open-frame rack, you must first install the open-frame rack mounting shelf.

To install the open-frame rack mounting shelf (see Figure 3):

  1. On the rear of each rack rail, partially insert a mounting screw into the highest hole specified in Table 3 for the open-frame rack mounting shelf.
  2. Install the open-frame rack mounting shelf on the rack. Hang the shelf over the mounting screws by using the keyhole slots located near the top of the shelf flanges.
  3. Partially insert screws into the open holes in the flanges of the open-frame rack mounting shelf.
  4. Tighten all the screws completely.

Overview of Installing a PTX5000 Using a Mechanical Lift

Before installing the PTX5000 using a mechanical lift, verify that you have prepared your site, unpacked the chassis from the shipping crate, and installed the mounting hardware.

Because of the PTX5000 router’s size and weight—up to 1,200 lb (544.3 kg) depending on the configuration— you must install the PTX5000 using a mechanical lift.

To install the PTX5000:

  1. Gather the tools required to install the PTX5000.
  2. Read the safety information in General Safety Guidelines and Warnings and PTX5000 Installation Safety Guidelines.
  3. Install the PTX5000 into the rack using a mechanical lift.

Tools Required to Install the PTX5000 Using a Mechanical Lift

Gather the tools required to install the PTX5000:

  • Mechanical lift

  • Phillips (+) screwdriver, number 2

Installing the PTX5000 By Using a Mechanical Lift

CAUTION:

Before installing the PTX5000:

  • Ensure that a mechanical lift is available for the installation. Because of the PTX5000 router’s size and weight—up to 1,200 lb (544.3 kg) depending on configuration—you must use a lift to install the chassis.

  • Have a qualified technician verify that the rack is strong enough to support the chassis weight and is adequately supported at the installation site.

  • Ensure that the rack is in its permanent location and is secured to the building.

  • Ensure that the installation site allows adequate clearance for both airflow and maintenance.

To install the PTX5000 by using a lift (see Figure 4, Figure 5, and Figure 6):

  1. Load the PTX5000 onto the lift, making sure that the chassis rests securely on the mechanical lift.
    CAUTION:

    Do not lift the PTX5000 by using the handles on the sides of the chassis. Use these handles only to help position the PTX5000.

  2. Using the lift, position the PTX5000 in front of the rack, centering it in front of the mounting shelf.
  3. Lift the chassis slightly above the surface of the mounting shelf, and position it as close as possible to the shelf.
  4. Carefully slide the PTX5000 onto the mounting shelf, so that the bottom of the chassis and the mounting shelf overlap by approximately 2 inches.
  5. With four people pushing on the front-mounting flanges, slide the PTX5000 onto the mounting shelf until the center-mounting brackets (open-frame racks) or front-mounting flanges (four-post racks) contact the rack rails. The shelves ensure that the holes in the center-mounting brackets and the front-mounting flanges of the chassis align with the holes in the rack rails.
  6. Visually inspect the alignment of the PTX5000. If the chassis is installed properly in the rack, all the mounting screws on one side of the rack should be aligned with the mounting screws on the opposite side, and the chassis should be level.
  7. Install a mounting screw into each of the mounting holes aligned with the rack, starting from the bottom.
  8. Move the lift away from the rack.

The holes in the center-mounting brackets are spaced at 3 U (5.25 in. or 13.3 cm).
