(Only Cisco 8818) Install the Pull bars on the Chassis

This procedure outlines the steps for installing the pull-bars on the 8818 chassis. The pull-bars serve as an aid for moving the chassis to the lifting device or closer to the rack where the chassis is installed.


Caution

Do not use these pull-bars to lift the chassis. Follow the orientation specified on the pull-bars to identify the correct right and left orientation.

Before you begin

  • The chassis must be unpacked.

  • Remove the pre-installed modules, including blanks and fan trays, and place them in a secure location to prevent damage to their connectors. Make sure the chassis is empty.

  • Keep the chassis on the pallet and leave the shipping brackets attached until the pull-bars are installed on the chassis.

Required tools and equipment:

  • Front and rear pull-bar kits


    Note

    The pull-bar kits are shipped with the chassis.

  • Phillips screwdriver with a torque capability (customer supplied)

Procedure

Step 1

Attach the front pull-bar to the front of the chassis at a position that is shown in the image.

Note

 

If the chassis has pre-installed blanks, then remove the required blanks to install the front pull-bar.

Examine the orientation of the front pull-bar and ensure that the right and left sides of the pull-bar are positioned correctly.

Use the screws (#6-32 x 0.375-in UNC captive screws) present in the plastic bag attached to the front pull-bar. Tighten three screws on each side of the pull-bar with enough torque to ensure the pull-bar is firmly attached to the chassis.

Step 2

Attach the rear pull-bar to the rear of the chassis at a position that is shown in the image.

Note

 

If the chassis has pre-installed fan trays, then remove the fan trays to install the front pull-bar.

Use the screws present in the plastic bag attached to the rear pull-bar:

  • Two screws (#10-32 x .375-in UNC captive screws) on the left side.

  • Two screws (#10-32 x .25-in UNC captive screws) on the right side.

Tighten two screws on each side of the pull-bar with enough torque to ensure the pull-bar is firmly attached to the chassis.

Note

 

If the chassis has pre-installed fan trays, then remove the fan trays to install the rear pull-bar.

Examine the orientation of the rear pull-bar and ensure that the right and left sides of the pull-bar are positioned correctly.

Figure 14. Remove Shipping Brackets from 8818 Chassis

Install Bottom-Support Rails

The bottom-support rails support the weight of the router chassis in the rack. To maximize the stability of the rack, you must attach these rails at the lowest possible rack unit (RU).

Procedure

Step 1

Position the vertical rack rails at 32" depth to match with the length of the bottom-support rails. Check spacing considerations.

  • Maintain at least 21 RU (36.75 inches [93.34 cm]) for 8812 chassis and 16 RU (28 inches [71.12 cm]) for 8808 chassis of vertical space above support rails.

  • Use 8800-ADJ-RAIL for an L-type rack and use 8800-RAIL-KIT for a U-type rack. The U-type rack (8800-RAIL-KIT) is used with racks whose rails do not fit at 32'' depth.

Step 2

Attach the bottom-support rail to the rack using a Phillips torque screwdriver on M6 x 19 mm or 12–24 x 3/4 inch screws for each end of the rail (as shown in the following figure) and tighten each screw to 40 in-lbs (4.5 N-m) of torque.

Note

 
Use at least three screws on each end of each bottom-support rail.

Step 3

Repeat Steps 1 and 2 to attach the other bottom-support rail to the rack.

Note

 
Make sure that the two bottom-support rails are level with one another. If they are not level, adjust the higher rail down to the level of the lower rail.

What to do next

Mount the chassis into the rack.

Transfer Chassis to a Mechanical Lifting Device

Procedure

Step 1

Place the mechanical lifting device in front of the chassis on the pallet (or on Line Card side) as shown.

Figure 20. Align the Lifting Device in Front of the Cisco 8818 Chassis with Pull-Bars Installed
Figure 21. Align the Lifting Device in Front of the Chassis on the Pallet - Other Chassis

Step 2

Prepare to use the mechanical lifting device by placing a piece of cardboard on the surface of the lift (to prevent scratching).

Step 3

Move the chassis carefully from the pallet onto the lifting device:

  • (Cisco 8818) With at least two or three people move the chassis carefully from the pallet using the pull-bars attached, onto the lifting device as shown.
    Figure 22. Move the Cisco 8818 Chassis Using the Pull-Bars on to the Lifting Device
  • (Other Chassis) With at least two or three people move the chassis carefully from the pallet onto the lifting device as shown.
    Figure 23. Move the Chassis on to the Lifting Device

What to do next

After moving the chassis to the room or area where you will install it, begin the procedure to mount the chassis into the rack.

Mount Chassis Into the Rack

To accommodate equipment racks with different mounting hole patterns, the chassis mounting brackets have groups of screw holes on either side. The mounting holes in the chassis mounting brackets are spaced so that one mounting hole in each hole group aligns with a corresponding hole in the equipment rack. By using the corresponding mounting hole (in the same hole group) on the opposite side of the chassis, you can level the chassis in the rack.


Note

  • To lift the chassis, use a mechanical lift. Do not use the handles on the side of the chassis. Use the side handles for only repositioning the chassis after it is already on the mechanical lift or in the rack or cabinet. In Cisco 8818 chassis with pull-bars installed, use the pull-bars to move the chassis.

  • Do not remove the blanks during rack installation. However, in case of Cisco 8818 chassis, the pre-installed modules and blanks are removed before installing the pull-bars.
