About PIX 520


I’ve got this PIX 520 the show version of which is below… I’m about to

install the PIX os 6.3, can I also install more interfaces, as per the PIX 6.3 OS I

should be able to go to 8 10/100 interfaces am I correct. ? Are these the same four

port and single port interfaces as the current PIX 525 / 515

Thanks and Regards

Re: About PIX 520

Sure, the only thing that would hold you back is if the pix is restricted but this looks to be unrestricted.
