The Router Shipping Package

Figure A-1 shows the router in an exploded view of the parts making up the

shipping package components.

Because of the weight and height of the router, the router shipping pallet

incorporates a scissor-jack platform. This scissor-jack platform enables a team of

two installers to remove a fully-loaded router from the pallet and insert it into an

equipment rack, or extract a fully loaded router from a rack, without removing any

of the components from the router chassis.

The router should be bagged to protect it against dust and electrostatic discharge

(ESD) and secured to the scissor-jack platform by four anchor clips. The anchor

clips are inserted into slots along the bottom edges of the router chassis side

panels and secured to the scissor-jack platform by four bolts. In turn, the

scissor-jack platform is secured to the shipping pallet by eight hold-down brackets

that are bolted to the top of the shipping pallet.

The shipping pallet consists of a U-shaped wood and foam pallet body and a wood

and foam pallet front bar. The pallet front bar fastens to the open end of the pallet

body to create the fourth bearing surface for the scissor-jack platform and to

complete the base needed to support the walls of the shipping container.

Appendix A Repackaging the Router

Repackaging the Routers

When the router and scissor-jack platform are installed on the pallet, the router

and scissor-jack platform are suspended over the well formed by the pallet body

and pallet front bar. When the scissor-jack platform is expanded to lower the

platform base and support the weight of the router, the bolts securing the

hold-down brackets to the top of the pallet can be removed. After the brackets

have been detached from the pallet, the router and scissor-jack platform can be

separated from the pallet by removing the pallet front bar from the pallet body and

pulling the pallet body away from the scissor-jack platform.

The side walls of the shipping container are formed by two U-shaped, interlocking

corrugated panels. The panels overlap to form the narrow ends of the container

and are locked together by twelve plastic locking clips inserted into holes in the

corrugated panels. Two foam inserts fit around the top of the router to act as a

protective cushion and add rigidity to the packaging scheme by serving as a fixed

buffer between the router, the corrugated side walls of the shipping container, and

the corrugated top cap that holds the side walls in place. With the corrugated top

cap installed, the entire shipping package is double-strapped end-to-end and

side-to-side to secure the shipping container and its contents to the pallet.

Appendix A Repackaging the Router

Repackaging the Routers

Removing the Router from the Rack

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

A fully-equipped router can weigh as much as 415 lb (188 kg). Because of the

weight and height of the router, Cisco provides a rack-mounting system for the

router that enables a team of two installers to extract a fully-loaded router from a

rack without removing any of the components from the router chassis. For

information on the router rack-mounting system, 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 the top-end weight 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:

•Powering Down the Router, page A-7

•Removing the Front Covers, page A-8

•Disconnecting RP Cables, page A-8

•Disconnecting Alarm Card Cables, page A-8

•Disconnecting Power Cables from the Power Shelf, page A-8

•Removing Components from the Chassis to Reduce Weight, page A-9

•Detaching the Supplemental Bonding and Grounding Connection, page A-10

•Removing the Router from the Equipment Rack, page A-11

Powering Down the Router

Power down the router as instructed in the “Powering Down the Router” section

on page 5-2.

OL-17440-01

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-45 or 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-input power

shelf, disconnect the AC-input power 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.

Appendix A Repackaging the Router

Repackaging the Routers

If your router is equipped with the DC-input power 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-equipped router can weigh as much as 415 lb (188 kg). To reduce the

top-end weight 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-input power supply weighs 12.7 lb (5.7 kg). By electing to remove the

three power supplies from the standard AC-input power shelf, you reduce the

top-end weight of the chassis by approximately 38.1 lb (17.1 kg). By electing to

remove the four power supplies from the optional AC-input power shelf, you

reduce the top-end weight of the chassis by approximately 50.8 lb (22.8kg)

Remove the AC-input power supplies as described in the “Installing AC-Input

Power Supplies” section on page 3-75.

Each DC-input power entry module weighs 6.4 lb (2.9 kg). By electing to remove

the four power entry modules from the power shelf, you reduce the top-end weight

of the chassis by approximately 25.6 lb (11.6 kg). Remove the DC-input power

entry modules as described in the“Removing DC-Input PEMs” section on

page 3-12.

OL-17440-01

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-end weight 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-preventive and

dust proof (for fiber-optic cards) 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 Upper Card Cage, page 3-18,

•Removing the Cards from the Lower Card Cage, page 3-20,

•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.
