Fibre Channel port specifications The Fibre Channel ports in the Core Switch 2/64 and SAN Director 2/128 support full duplex link speeds at 2.125 or 1.0625 Gb/s 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) and optical LWL (long wavelength: 1270-1350 nm) 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). CP card specifications CP card specifications listed in this section include: • Memory specifications, page 143 • Battery specifications, page 144 • Terminal serial port specifications, page 144 • Modem serial port specifications, page 145 Memory specifications CP card memory specifications include: • Main memory: 256 MB SDRAM (32 bits wide) • Flash memory: • User flash: 16 MB of 16-bit wide memory, stored in two 8-MB banks • Compact flash: 256 MB, partitioned in two 128-MB sections • Boot flash: 512 KB of 8-bit for system boot The centralized memory maximizes the overall switch throughput by guaranteeing full transmit at all times.
