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
