The PRE3 has specific Cisco IOS software requirements.
Table 3 shows the minimum required Cisco IOS software for the PRE3.
Use the show version command to display the system software version that is currently loaded and
running.
If the output of the show version command indicates that the Cisco IOS software is a version earlier than
the version identified as the minimum Cisco IOS software release in
Table 3 , check the contents of the
CompactFlash memory to determine if the required images are available on your system.
The output of the show flash command provides a list of all files stored in the CompactFlash memory.
If the correct software version is not installed, contact Cisco Customer Service (see the
“Obtaining
Technical Assistance” section on page 37 ).
Installation Guidelines
This section contains guidelines for the following:
• A new installation
• A replacement installation
• The required tools and equipment
The PRE3 is hot-swappable, which means you can remove and replace a PRE3 while the system is
operating—if you have a standby (redundant) PRE3 installed in the chassis. This feature allows you to
add, remove, or replace a PRE3 while the system maintains all routing information and ensures session
preservation.
Caution Replacing the active PRE3 in a non-redundant chassis (no standby PRE3) causes a system shutdown and
stops all traffic. If possible, alert all subscribers that the system will not be functioning during the
replacement.
Caution To prevent electrostatic discharge (ESD) damage, handle the PRE3 by the faceplate or the card carrier
edges only. Avoid touching the printed circuit board and its components, or any connector pins.
New Installation Guidelines
If you are replacing the PRE3 in a non-redundant system, you must configure the PRE3 using the
configure command. For configuration information, refer to the
“Configuring a PRE3” section on
page 14 .
