Memory specifications
The Brocade 7800 has three types of memory devices:
• Main memory (DDR2 SORDIMM SDRAM) - 2 GB
• Boot flash - 4 MB
• Compact flash - 1 GB
Fibre Channel port specifications
The Fibre Channel ports in the Brocade 7800 are compatible with SWL, LWL, and ELWL SFP
transceivers. The strength of the signal is determined by the type of transceiver in use.
The ports meet all required safety standards. For more information about these standards, see
Regulatory compliance on page 53.
The ports are capable of operating at 1-, 2-, 4-, or 8-Gbps and are able to auto-negotiate to the
maximum link speed.
GbE port specifications
The GbE ports in the Brocade 7800 are compatible with short range (SR) and long range (LR) copper
or optical SFP transceivers. The strength of the signal is determined by the type of transceiver in use.
The 10 GbE ports are optical only.
The ports meet all required safety standards. For more information about these standards, see
Regulatory compliance on page 53.
The GbE ports are capable of operating at 1-Gbps. The 8 virtual FCIP Fibre Channel links over each
physical GbE connection share this bandwidth.
