We are upgrading or PIX525 to gig E. I need to find what the memory requirements are to add those cards. This is all I could find:
"We highly recommend that you use Livengood Gigabit Ethernet cards in systems with a 64-bit/66 MHz PCI bus; for example, in a PIX 535. (If you use the Livengood Gigabit Ethernet cards in a PIX Firewall, the system RAM should be at least 128 MB.) For a PIX Firewall with only a 32-bit/33 MHz bus, such as the PIX 520 and PIX 525, we recommend that you use Wiseman Gigabit Ethernet cards."
I couldn't say yes or no to this becuase I mostly work on 515's but it can't hurt to upgrade your memory to keep track of the potential connections, if infact your are needing gigabit cards to support the amount of traffic flowing through your 525.
