Performance Route Processor Installation and Configuration Guide
OL-11656-01
Preparing for Installation
• Cisco equipment operates safely when it is used in accordance with its
specifications and product usage instructions.
• If you plan to replace a PRP, back up your current configuration file to a
remote server or to Flash memory before you remove the PRP. This prevents
you from having to reenter all your current configuration information
manually. To back up the file, copy your configuration file to a Flash disk or
access a remote server.
Preventing Electrostatic Discharge
Electrostatic discharge (ESD) damage, which can occur when electronic cards or
components are improperly handled, results in complete or intermittent failures.
Electromagnetic interference (EMI) shielding is an integral component of the line
card. Cisco recommends using an ESD-preventive strap whenever you are
handling network equipment or one of its components.
The following are guidelines for preventing ESD damage:
• Always use an ESD-preventive wrist or ankle strap and ensure that it makes
good skin contact. Connect the equipment end of the connection cord to an
ESD connection socket on the router or to bare metal on the chassis.
• Handle PRPs by the captive installation screws, the provided handle, ejector
levers, or the line card metal carrier only; avoid touching the board or
connector pins.
• Place removed PRPs board-side-up on an antistatic surface or in a static
shielding bag. If you plan to return the component to the factory, immediately
place it in a static shielding bag.
• Avoid contact between the PRPs and clothing. The wrist strap only protects
the board from ESD voltages on the body; ESD voltages on clothing can still
cause damage.
Warning
For safety, periodically check the resistance value of the ESD strap. The
measurement should be between 1 and 10 megohms.
