PIX 520
The PIX 520 is an odd bird. It was advised as the high-end PIX platform,
with the PC-style rack-mount anatomy and a advanced mix of accessible media cards,
including Token Ring and fiber. Like the beforehand PIXs, the 520 comes with a DB9
console anchorage and a diskette drive; it is based on the 200MHz Intel Pentium
MMX but with 128MB of RAM. Additionally abnormal is the licensing: Like the 501, the
520’s authorization is based on the cardinal of users. For an access PIX, you would purchase
PIX-CONN-128, which would acquiesce 128 accompanying users.There were
license upgrades to 1024 users or absolute users.
Having the diskette drive is abnormally convenient. Although it uses up real
estate in the rack, it allows you to accept a accessible cossack average in case the network
goes bottomward or is contrarily inaccessible;TFTP servers are not required.
It additionally allows you to readily displace the countersign (by booting the appropriate
password-clearing binary) or restore to a accepted acceptable condition. Of course, these
features are now accomplished through adapted arrangement administration tools, such
as CiscoWorks or the PIX Firewall Manager.
