QLogic 8200 Dual Port 10GbE SFP+ VFA
io3 Enterprise Flash Adapters
io3 Enterprise Value Flash Adapters
io3 Enterprise Mainstream Flash Adapters
P3700 NVMe Enterprise Performance Flash Adapters
The x3550 M5 Thermal Kit is not needed if two processors are installed, because the second processor
includes these fans.
The COM Port Bracket, part number 00KA161, is used for mounting the external serial port on the rear of
the x3550 M5. This option includes the bracket and the cable. The COM Port option is mounted in place of
