NVRAM and Boot Flash
The NVRAM in the Cisco 7301 is 512 KB.
Boot Flash on the Cisco 7301 has been doubled over previous Cisco 7000 Series routers to 32 MB. This increase in size allows the end user to
keep a full boot image in boot Flash or have plenty of room for multiple log file locations or backup configuration files.
Compact Flash Memory
The Cisco 7301 also includes a single 64-MB default compact Flash for removable Flash storage, upgradable to 256 MB. The chassis are also
formatted using the ATA standard file system format so they can be read in other ATA routers and PC systems with a simple compact Flash to
PCMCIA adapter module or compact Flash reader. It is large enough to hold at least two Cisco IOS Software images.
Console and Auxiliary Ports
The Cisco 7301 has built-in console and auxiliary ports on the front end of the chassis.
Software
The Cisco 7301 supports the following Cisco IOS releases:
• 12.2(11)YZ. This is a special release of 12.2(11)S. Its migration path is the third release of 12.2S.
• 12.2(13)B required to support 16,000 subscribers.
• 12.3(2)T when the release is available.
