Replacing or Upgrading the Chassis

Replacing or Upgrading the Chassis

The RSP is a required system component and should only be removed when the system is not

operating, although power can be on to the chassis. All interface processors support online insertion

and removal (OIR); however, after installing an interface processor, you must wait at least 15

seconds for the system to reinitialize the interfaces before installing the next interface processor.

Therefore, it is more efﬁcient to leave the power off until all components are moved into the new

chassis, then start up the system and check the entire installation.

If you are installing the new chassis in an equipment rack, proceed to the next section. Otherwise,

proceed to the "Moving Processor Modules from the Old Chassis to the New Chassis" section on

page 18.

Replacing a Rack-Mounted Chassis

This section describes how to replace a chassis that is installed in an equipment rack. The order in

which you remove the existing system, install the new chassis, and replace the components will vary

depending upon the space available in the rack and in the work area.

Some rack conﬁgurations, such as an enclosed rack or a rack with a power strip that limits access,

prohibit the normal installation sequence of ﬁrst installing the chassis in the rack and then installing

the cable-management brackets before installing the processor modules. In these situations, you can

move all the components into the new chassis before installing it in the rack, but ensure that you

follow the safety guidelines for lifting and working with electrical equipment that are provided in

the section "Safety Guidelines" beginning on page 8.

If there is sufﬁcient space available in the same rack (or an adjacent rack) and you have a rack-mount

kit available, you can install the new (replacement) chassis before you remove the existing system.

You can minimize downtime and avoid having to disconnect network interface cables by leaving the

existing system operating while you install the empty replacement chassis in the rack. Also, an

empty chassis is signiﬁcantly lighter and easier to handle than one that is fully conﬁgured. Just

ensure that both chassis, when installed, will be close enough to avoid straining the interface cables

connected to the interface processors.

If you must remove the existing system to make room for the replacement chassis, or if you need the

existing rack-mounting hardware to mount the new chassis, you will have to disconnect all network

interface cables before removing the existing system from the rack. You can leave the system

components in the old chassis until after you install the new, empty chassis in the rack.

12 Cisco 7513 and Cisco 7576 Chassis Replacement and Upgrade Instructions

If you plan to mount or replace the chassis in an equipment rack, you also need the following

tools:

— Number 2 phillips screwdriver

— 1/4-inch and 3/16-inch, ﬂat-blade screwdrivers

— ACS-7000RMK(=) rack-mount kit (with hardware) for the chassis (this kit also works for

the Cisco 7000 chassis)

Whenever you remove or install processor modules, have the following equipment on hand to

help prevent ESD damage:

— Antistatic mat or antistatic foam pad in case you need to put one of the processor modules

down

— Your own ESD-preventive strap or the disposable ESD strap that is included with all spares
