pix 535 failover problem?

[zoushan]

Hello,everyone:

I have a PIX-535-R-BUN and a PIX-535-FO-BUN, I want to know whether the two pixs can configure as failover mode ? I read the doc of pix, It say that The PIX 515, PIX 525, and PIX 535 can only be used for failover if you have the optional "UR" license. Becaust the pix535-r-bun is restricted SW, I am worry about it can work as failover mode.

Use the command "show version" and check the failover feature. You should find that the UR has failover enabled and the R may also. If both do then you can use these as a failover pair.
