100 Mbps or 1 Gbps. On the Copper models, there are 4 designated SFP
Combination Ports that be used instead of 4 designated RJ45 Combination Ports.
Into a physical port, only supported Brocade-branded fiber-optic transceivers can be
used. The SFP-compliant fiber-optic modules provide an optical transceiver or
physical medium dependent (PMD) interface for single or multi-mode fiber that can
be used with the LAN physical layer (PHY) and support optical monitoring
capabilities. Types of Brocade-branded SFP transceivers for the 100/1000 1 GbE
(SFP) interface modules include:
v
1000BaseT SFP Copper, 1 Gbps up to 100 m over CAT5 or higher cabling,
RJ-45 connector
v 1000Base SX 850 nm SFP optic, 1 Gbps up to 550 m over multi-mode fiber, LC
connector
v 1000Base LX 1310 nm SFP optic, 1 Gbps up to 10 km over single-mode fiber,
LC connector
v 1000Base LHA 1550 nm SFP optic, 1 Gbps up to 70 km over single-mode fiber,
LC connector
v 100Base FX 1310 nm SFP optic, 100 Mbps up to 2 km over multi-mode fiber, LC
connector
10–gigabit Ethernet ports: The B50C models contains two physical ports through
which you can connect the switch to other network devices at speeds of 10 GbE.
Only Brocade-branded fiber-optic transceivers can be used in these ports. The
XFP-compliant fiber-optic modules provide an optical transceiver or physical
medium dependent (PMD) interface for single or multi-mode fiber that can be used
with the LAN physical layer (PHY), and support optical monitoring capabilities.
Types of Brocade-branded XFP transceivers for the 10 GbE ports include:
v
Short Reach, 850 nm serial pluggable XFP optic, 10 Gbps up to 300 m over
multi-mode fiber, LC connector
v Long Reach, 1310 nm serial pluggable XFP optic, 10 Gbps up to 10 km over
single-mode fiber, LC connector
v
Extended Reach, 1550 nm serial pluggable XFP optic, 10 Gbps up to 40 km over
single-mode fiber, LC connector
v 10 Base CX4, XFP transceiver, 10 Gbps up to 15 km, CX connector
Port regions
Ports on the switches are grouped into regions. For a few features, such as port
monitoring and unknown unicast configurations, you will need to know the region to
which a port belongs. However, for most features, a port’s region does not affect
configuration or operation of the feature. If a port’s region does affect configuration
or operation of a feature, it is noted and described in the appropriate feature section
of this guide.
v
Ports 1/1 -1/24
v Ports 1/25 - 1/48
v
Port 1/2 (10-GbE uplink port on the B50C models only)
v Port 2/2 (10-GbE uplink port on the B50C models only)
Power supplies
Each switch comes with one alternating-current (AC) power supply. All models have
two power supply slots, enabling you to install a second power supply for
redundancy.
