DRAFT: BROCADE CONFIDENTIAL
Memory specifications
The Brocade 6520 has three primary types of memory devices, boot flash, compact flash, and
main memory. The size of each is listed in the following table.
Fibre Channel port specifications
The Fibre Channel ports in the Brocade 6520 are compatible with SWL, LWL, and ELWL SFP+ (for
16 Gbps performance) 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 38.
The ports are capable of operating at 2, 4, 8, or 16 Gbps depending on SFP+ models and are able
to autonegotiate to the maximum link speed.
The first eight ports on the switch can be configured to run at 10 Gbps with the appropriate license
and transceivers.
Serial port specifications
The serial port is located on the port side of the switch. The Brocade 6520 uses an RJ45 connector
for the serial port. An RJ45 to RS-232 adaptor is also provided with the switch
.
NOTE
To protect the serial port from damage, keep the cover on the port when not in use.
The serial port can be used to connect to a workstation to configure the switch IP address before
connecting the switch to a fabric or IP network. The serial port’s parameters are fixed at 9600
baud, 8 data bits, and no parity, with flow control set to None.
Table 10 lists the serial cable pinouts.
