Chapter 7 PIX 535

Installing a Circuit Board in the PIX 535

There are nine circuit board slots (see Figure 7-10) using three separate buses for the PIX 535.

The slots and buses are configured as follows:

•Slots 0 and 1—64-bit/66 MHz Bus 0

•Slots 2 and 3—64-bit/66 MHz Bus 1

•Slots 4 to 8—32-bit/33 MHz Bus 2

For optimum performance and throughput for the interface circuit boards, you must use the following guidelines:

•A total of two 10/100 Fast Ethernet interfaces, and support for up to twelve additional 10/100 Fast Ethernet or nine Gigabit Ethernet interfaces are configurable with the unrestricted license

•PIX-1GE-66 (66 MHz) circuit boards can be installed in any slot, but should be installed in the 64-bit/66 MHz Bus first. Up to eight PIX-1GE-66 circuit boards can be installed.

•The FE circuit board (33 MHz) can be installed in any bus or slot (32-bit/33 MHz or

64-bit/66 MHz). Up to eight single-port FE circuit boards or up to two four-port FE circuit boards can be installed.

–The four-port FE circuit board should only be installed in the 32-bit/33 MHz Bus.

Note The numbering of the FE circuit boards in monitor mode begins at the 32-bit slots; do not install any FE circuit boards in the 64-bit slots.

•Do not mix the 33 MHz circuit boards with the 66 MHz GE circuit boards on the same

64-bit/66 MHz bus (Bus 0 or Bus 1). The overall speed of the bus will be reduced by the lower speed circuit board.

•The VPN Accelerator circuit board should only be installed in the 32-bit/33 MHz Bus.
