Port specifications
Fibre Channel port specifications
The Fibre Channel ports in the router 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 are capable of operating at 1-, 2-, or 4-Gbit/sec and
are able to auto-negotiate to the maximum link speed.
GbE port specifications
The GbE ports in the router are compatible with SWL, LWL, and ELWL SFP
transceivers. The strength of the signal is determined by the type of transceiver in
use. These ports are capable of operating at up to 50 Mbps in the base
configuration, and up to 1 Gbps with the upgrade license. The virtual FCIP Fibre
Channel links over each physical Ethernet connection share this bandwidth. A
single FCIP link per Ethernet port is available in the base router, with up to eight
links per channel available with the upgrade license.
Serial port specifications
The serial port (with an RJ-45 connector) is located on the port side of the router.
An RJ-45 to DB9 adaptor is also provided with the router.
Note: To protect the serial port from damage, keep the cover on the port when not
in use.
