Flash Memory Image Checksum Values
Software releases 2.0.0 and above require a 32 MB network processor (NP).
Software Release 2.0.5 is the minimum software revision necessary for the support of redundant
switches.
Flash Memory Image Checksum Values
Every time you install a card in a slot of the system, you must verify that it has the correct flash
memory checksum and upgrade flash if necessary. The procedures are given in the LightStream 2020
Hardware Reference and Troubleshooting Guide. Use the bash command sysver -a to display flash
checksums. The checksums for this new release are as follows:
Network Processor: Flash Image Checksum: 0xC1DE
Switch Card 1: Flash Image Checksum: 0x5D00
Switch Card 2: Flash Image Checksum: 0x64A2
Low Speed Card: Flash Image Checksum: 0x181C
Medium Speed Card: Flash Image Checksum: 0xA7FC
Packet Line Card: Flash Image Checksum: 0x0339
Cell Line Card: Flash Image Checksum: 0xE782
If the flash checksum is 0x64A2 for a Release 2 switch card or 0x5D00 for a Release 1 switch card,
then the specified switch card already has the latest flash image.
Note The label Switch Card 1 denotes Release 1 of the switch card, and the label Switch Card 2
denotes Release 2 of the switch card.
Special Considerations
This section describes special considerations that apply to Release 2.0.9 of the LightStream 2020

with the product by LightStream 2020 customers, Cisco developers, and Cisco software quality
assurance personnel.
Most of the special considerations here are given Cisco case numbers. If you contact Cisco Systems
about any of these special considerations, please refer to the case number.
