connectors.

vary depending on the catalog number.

Feature Description
Power and relay connectors You connect the DC power and alarm signals to the switch through two front panel connectors. One connector provides
primary DC power (Pwr A) and a second connector (Pwr B) provides secondary power. The two connectors are physically
identical and are on the right side of the front panel.
The 6-pin alarm connector provides an interface for an output alarm relay and two input alarms. The output alarm can be
activated for environmental, power supply, and port status alarm conditions and can be configured to indicate an alarm
with one normally open and one normally closed (form C) contact. From the CLI, you can configure the output alarm to be
normally energized or normally de-energized. The input alarm terminals can be used to activate alarms for any conditions
external to the switch.
The switch can operate with a single power source or with dual power sources. When both power sources are operational,
the switch draws power from the DC source with the higher voltage. If one of the two power sources fail, the other
continues to power the switch.
Console port For configuring, monitoring, and managing the switch, you can connect a switch to a computer through the console port
and a RJ45-to-DB-9 adapter cable or a mini USB cable (neither cables are supplied with the switch). The mini USB driver is
available in the firmware download section at
http://www.rockwellautomation.com .
Dual-purpose uplink ports The two dual-purpose uplink ports available on some models can each be configured for RJ45 (copper) or SFP (fiber) media
types. Only one of these connections in each of the dual-purpose ports can be active at a time. If both ports are connected,
the SFP module port has priority.
You can set the copper RJ45 ports to operate at 10, 100, or 1000 Mbps (1000Mbps is not supported on all modules with
combo ports), full-duplex or half-duplex. You can configure them as fixed 10, 100, or 1000 Mbps (Gigabit) Ethernet ports
and can configure the duplex setting.
You can use approved Gigabit (or 100 Mbps) Ethernet SFP modules to establish fiber-optic connections to other switches.
These transceiver modules are field-replaceable, providing the uplink interfaces when inserted in an SFP module slot. You
use fiber-optic cables with LC connectors to connect to a fiber-optic SFP module. These ports operate only in full-duplex.
10/100 ports You can set the 10/100 ports to operate at 10 or 100 Mbps, full-duplex or half-duplex. You can also set these ports for
speed and duplex autonegotiation in compliance with IEEE 802.3-2002. (The default setting is autonegotiate.)
When set for autonegotiation, the port senses the speed and duplex settings of the attached device. If the connected
device also supports autonegotiation, the switch port negotiates the best connection (that is, the fastest line speed that
both devices support and full-duplex transmission if the attached device supports it) and configures itself accordingly. In
all cases, the attached device must be within 100 m (328 ft) of the switch.
