SAN Switch 2/16 Version 3.1.x Installation Guide
Memory Specifications
The switch utilizes the following memory.
■
Main Memory (SDRAM): 32 MB per switch
■
Flash Memory: Dual 8 MB
■
Boot Flash: 512K bytes of 8-bit for system boot
The centralized memory maximizes the overall switch throughput by guaranteeing
full transmit and receive bandwidth to all Fibre Channel ports at all times.
Note:
For dust and ESD (electrostatic discharge) protection, a cover is provided for the
Serial port and should be kept on the port whenever the Serial port is not in use.
The Serial port can be used to connect to a computer workstation to configure the
switch IP address without connecting to the fabric. The Serial port’s parameters
are 9600 baud, 8 data bits, no parity, 1 stop bit, and no flow control.
The port requires a straight Serial cable with a female 9-pin subminiature-D
connector. Only pins 2, 3, and 5 are supported; if pin 7 is used, the signal must
always be driven high, using the pinouts listed in
Table 9
