4 Memory Specifications Memory Specifications The Brocade 5000 has three types of memory devices: - Boot flash: 4 MB - Compact flash: 1 GB - Main memory (SDRAM): 256 MB Fibre Channel Port Specifications The Fibre Channel ports in the Brocade 5000 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 29. The ports are capable of operating at 1, 2, or 4 Gbit/sec and are able to autonegotiate to the higher of 1, 2, or 4 Gbit/sec. Serial Port Specifications The serial port is located on the port side of the switch. The Brocade 5000 uses an RJ-45 connector for serial port. ATTENTION 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. This connector is for initial IP address configuration and for recovery of the switch to its factory default settings if Flash memory contents are lost. The serial port is not intended for performance of normal administration or maintenance functions. You should only use this port to connect a terminal to the port to re initialize the switch defaults, restoring the switch to its factory configuration. This is required to restore switch passwords to a known state and allow you to assign an IP address to the switch. Table 8 lists the serial cable pinouts.
