Fibre Channel port specifications
The fibre channel ports in the 4/256 SAN Director support full duplex link speeds at 4.25, 2.125 or
1.0625 Gb/sec inbound and outbound, automatically negotiating to the highest common speed of
all devices connected to the port. 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.
The ports are compatible with optical SWL (short wavelength: 780-850 nm), optical LWL (long
wavelength: 1270-1350 nm), and Extended Long Wavelength (ELWL) laser transmitter 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 are universal and self-configuring, capable of becoming F_Ports (fabric ports), FL_Ports
(fabric loop enabled), or E_Ports (expansion ports).
The ports meet all required safety standards. For a listing of these standards, refer to ”Regulatory
compliance notices” on page 183.
CP card specifications
CP card specifications include:
• Memory specifications, page 207
• Battery specifications, page 208
• Terminal serial port specifications, page 177
• Modem serial port specifications, page 209
Memory specifications
Each CP card has the following memory:
• Main memory: 512 MB SDRAM (72 bits wide)
• Flash memory:
• User flash: 16 MB of 16-bit wide memory, stored in two 8-MB banks
• Compact flash: 1 GB, partitioned in two 512-MB sections
• Boot flash: 512 KB 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.
