Memory Specifications
The FC Entry Switch 8B and FC Switch 8B have the following memory:
•
Main memory (SDRAM): 32 MB
•
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.
Optical Port Specifications
The optical ports in the FC Entry Switch 8B and FC Switch 8B are compatible with SWL (short
wave-length) and LWL (long wave-length) SFPs (small form factor pluggable media) and
SFP-compatible cables. The strength of the signal is determined by the type of SFP in use.
The ports meet all required safety standards. For more information about these standards, see
Regulatory Compliance

.
The ports are capable of operating at 2.125 Gbps or 1.0625 Gbps. Each port has a SerDes
(serializer/deserializer) that accepts 10-bit wide parallel data and serializes it into a high-speed
serial stream. The parallel data is expected to be “8B/10B” encoded data or equivalent.
Serial Port Specifications
The serial port has an RS-232 connector, and is located in the SFP media side of the switch.
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.
