REVIEW DRAFT —CISCOCONFIDENTIAL

Removing the Router from the Rack

This section describes how to remove the router from the equipment rack.

A fully-equippedrouter can weigh as much as 415 lb (188 kg). Because of the weight and height of the router, Cisco provides arack-mountingsystem for the router that enables a team of two installers to extract afully-loadedrouter from a rack without removing any of the components from the router chassis. For information on the routerrack-mountingsystem, refer to“A fully equipped router with an optional two-level AC-input power shelf can weigh as much as

440 pounds (200 kg). The router ships on a scissor-jack platform that enables two people to install a fully loaded router into a rack without removing any of the components from the chassis.” section on page 3-2.

Note As an option, you can elect to remove some of the components from the chassis to reduce thetop-endweight of the chassis and lower the center of gravity, making the chassis more stable as you move it. The procedures for removing components are described in the“Unpacking and Positioning the Router” section on page 3-3.

Procedures in the following sections describe the steps for removing the chassis from the equipment rack:

Removing the Front Covers

Remove all of the front covers from the chassis as instructed in the “Removing the Chassis Front Covers” section on page 3-7.You will install them on the chassis after it has been secured on the shipping pallet?

Disconnecting RP Cables

You must disconnect any cables that are connected to the RP console port, auxiliary port, or either of the Ethernet ports, RJ-45or MII. Identify each of the RP cable connections and write them down on a piece of paper before you disconnect the cables. After disconnecting the cables, remove them from the chassis and place them safely aside.

Refer to the following descriptions in Chapter 2, “Preparing for Installation.” for information on RP cables:

GRP Console and Auxiliary Port Connection Guidelines, page 2-24

PRP Console and Auxiliary Port Connection Guidelines, page 2-27

GRP Ethernet Connection Equipment, page 2-29

PRP Ethernet Connection Equipment, page 2-36

Disconnecting Alarm Card Cables

You must disconnect any cable that is connected to the external alarm port on either or both of the alarm cards. Identify the alarm cable connections and write them down on a piece of paper before you disconnect the cables. After disconnecting the cables, remove them from the chassis and place them safely aside.

For information on alarm card cables, refer to the “Alarm Card Connection

Guidelines” section on page 2-33.

Disconnecting Power Cables from the Power Shelf

If your router is equipped with either the standard or optional AC-inputpower shelf, disconnect theAC-inputpower cords from their receptacles on the back panel of the power shelf as instructed in the“Removing and Installing the Standard One-Level AC-Input Power Shelf” section on page 5-32.

If your router is equipped with the DC-inputpower shelf, disconnect the eight source DC positive and negative power cables and the single ground cable from the terminal studs on the back panel of the power shelf as instructed in the“Removing and Installing a DC-Input Power Shelf” section on page 5-54.

Removing Components from the Chassis to Reduce Weight

A fully-equippedrouter can weigh as much as 415 lb (188 kg). To reduce thetop-endweight of the chassis and lower the center of gravity, which might make the chassis more stable as you move it, you may choose to remove some of the components from the chassis.

Procedures in the following sections describe the steps for removing some of the router components:

Removing Power Modules, page A-9

Removing the Blower Modules, page A-10

Removing the Cards from the Chassis Card Cages, page A-10

Removing Power Modules

Each AC-inputpower supply weighs 12.7 lb (5.7 kg). By electing to remove the three power supplies from the standardAC-inputpower shelf, you reduce thetop-endweight of the chassis by approximately 38.1 lb (17.1 kg). By electing to remove the four power supplies from the optionalAC-inputpower shelf, you reduce thetop-endweight of the chassis by approximately 50.8 lb (22.8kg) Remove theAC-inputpower supplies as described in the“Installing AC-Input Power Supplies” section on page 3-75.

Each DC-inputpower entry module weighs 6.4 lb (2.9 kg). By electing to remove the four power entry modules from the power shelf, you reduce thetop-endweight of the chassis by approximately 25.6 lb (11.6 kg). Remove theDC-inputpower entry modules as described in the“Removing DC-Input PEMs” section on

page 3-12.

Removing the Blower Modules

The blower module weighs 20.5 lb (9.3 kg). By removing the upper blower module from the chassis, you reduce the top-endweight of the chassis by the weight of the blower module. Unless you plan to strip all components to reduce the overall weight of the chassis so you can shift the chassis by lifting it manually, there is no advantage in removing the lower blower module. Remove the blower modules as described in the“Removing the Blower Modules” section on

page 3-14.

Removing the Cards from the Chassis Card Cages

Unless you plan to strip all components to reduce the overall weight of the chassis so you can shift the chassis by lifting it manually, there is no advantage in removing the cards from the card cages. Reducing the overall weight of the chassis is offset by the requirement to store the cards in an ESD-preventiveand dust proof (forfiber-opticcards) environment.

If you elect to remove the cards from the chassis card cages, remove the cards as described in Chapter 3, “Installing the Router.”

Removing the Cards from the Switch Fabric Card Cage, page 3-22

Detaching the Supplemental Bonding and Grounding Connection

If your router has one or more bonding and grounding cables attached to any of the bonding and grounding receptacles on the chassis, you must detach these cable lugs from the chassis before you remove the chassis from the equipment rack.

Detach the bonding and grounding cable lugs from the chassis as instructed in the “Detaching the Supplemental Bonding and Grounding Connection” section on page 5-104.
