12 Appendix C  Repacking the router

Removing cables from the router

Before repacking the router, remove all cables such as the power cords, console cable, twisted pair cables, optical fibers, and grounding cable from the router.

Removing the power cords

1.     Switch off the circuit breakers at the input ends of all power cords.

2.     Wear an ESD wrist strap, and make sure it makes good skin contact and is reliably grounded.

3.     Remove power cords.

¡     For an AC power cord, remove the cable tie, and then remove the power cord connector.

¡     For a DC power cord, loosen the screws on the power cord connector, and then remove the connector.

4.     Perform the same step to remove the other power cords.

Removing the console cable

1.     Pull the RJ-45 connector of the console cable out from the console port on the router.

2.     Pull the DB-9 connector of the console cable out from the serial port on the PC or the terminal.

Removing the grounding cable

1.     Loosen the two screws from the grounding point at the rear bottom of the chassis, and then remove the grounding cable from the chassis.

2.     Use a wrench to remove the hex nut from the grounding post on the grounding strip, and remove the other end (ring terminal) of the grounding cable from the grounding post.

Removing the twisted pair cables and optical fibers

You must remove all twisted pair cables and optical fibers from the ports on the router.

 

	NOTE: After pulling out an optical fiber from a transceiver module, cover the connector of the optical fiber with a dust cap to keep the connector clean.

 

Repacking the FRUs

Repacking power supplies

	CAUTION: To avoid device damage and bodily injury, switch off the circuit breakers at the input ends of all power cords and remove all the power cords before removing power supplies.

 

To repack a power supply:

1.     Prepare the original packing materials, including the anti-static bag, packing foam, and packing box for a power supply. Make sure these packing materials are clean, dry, and not damaged.

2.     Remove the power supply from the chassis.

For the power supply removal procedure, see "Replacement procedures."

3.     Put the removed power supply into the anti-static bag.

4.     Place the power supply wrapped in the anti-static bag into the packing foam.

5.     Place the power supply and the packing foam in the packing box, and seal the box with tape.

6.     Perform the same steps to repack the other power supplies.

Repacking the modules

1.     Prepare the original packing materials, including the anti-static shielding bag, packing foam, and packing box, for a module. Make sure these packing materials are clean, dry, and not damaged.

2.     Remove the transceiver modules from the modules.

If no transceiver module is installed, skip this step.

For information about how to remove a transceiver module, see "Replacement procedures."

3.     Remove a module from the chassis.

If a filler panel is provided for the module slot, install the filler panel in the slot after you remove the chassis from the rack.

For information about how to remove a module and install a filler panel, see "Replacement procedures."

4.     Put the removed module into an anti-static bag.

For a module provided with a metal protection box, install the metal protection box for it before putting it into an anti-static bag.

5.     Place the module wrapped in the anti-static bag into the packing foam.

6.     Put the module and the packing foam into the packing box, and seal the box with tape.

7.     Perform the same steps to repack the other modules.

Repacking the fabric module slot filler panels

1.     Prepare the original packing materials, including the packing bag, packing foam, and packing box, for a fabric module slot filler panel. Make sure these packing materials are clean, dry, and not damaged.

2.     Remove the fabric module slot filler panel.

3.     Place the removed fabric module slot filler panel in the packing bag.

4.     Place the fabric module slot filler panel wrapped in the packing bag into the packing foam.

5.     Place the fabric module slot filler panel and the packing foam in the packing box, and seal the box with tape.

6.     Perform the same steps to repack the other fabric module slot filler panels.

Repacking the router chassis

Removing the chassis from the rack

IMPORTANT: ·     The router is high and heavy. As a best practice, remove the fan trays from the chassis before removing the chassis from the rack. Place the removed fan trays on an antistatic mat. ·     As a best practice, use the dolly shipped with the chassis to move the device.

 

To remove the chassis from the rack:

1.     Prepare the original packing components for the chassis, including the dolly, pallet base, packing bag, and crate. Make sure they are clean, dry, and not damaged.

2.     Place the dolly at a location where you can move the chassis easily.

3.     Use a Phillips screwdriver to loosen the screws that attach the mounting brackets to the rack.

4.     Use a minimum of four people to slide the chassis out of the rack along the slide rails. When most part of the chassis is out from the slide rails, lift up the chassis by holding the chassis handles to completely remove the chassis from the rack.

5.     Place the chassis on the dolly.

Repacking the router chassis

1.     Place the chassis on the dolly.

2.     Use L-shaped brackets to secure the chassis to the dolly, as shown in Figure12-1.

Figure12-1 Using L-shaped brackets to secure the chassis to the dolly

 

3.     Reinstall the removed fan trays on the chassis.

4.     Move the router to a location suitable for repacking.

5.     Attach the elevator plate to the ballet, as shown in Figure12-2.

Figure12-2 Attaching the elevator plate to the pallet

 

6.     Push the router to the pallet over the ramp with the rear of the chassis facing the pallet.

7.     Adjust the levelling feet of the dolly so that the levelling feet support the router securely.

8.     Use L-shaped brackets to secure the dolly to the pallet.

9.     Cover the chassis with the packing bag from top down, and then tape the bag to the plastic film.

10.     Place the accessory boxes around the chassis bottom and use tape to secure the boxes to the chassis.

11.     Remove the U-shaped fasteners from the pallet and install them on the ramp. Then place the ramp in its position and use tape to secure the ramp to the chassis.

12.     Place the packing foams around and on the top of the chassis and then use tape to secure them to the chassis.

13.     Install the four side panels and top panel of the crate.
