The 10/100/1000 Ethernet ports on the switches use RJ-45 connectors.

Note	Connector pins 1, 2, 3, and 6 are used for PoE.

The illustration below shows an LC style connector that is used with the SFP Module slots. It is a fiber-optic cable connector.

Warning

Invisible laser radiation may be emitted from disconnected fibers or connectors. Do not stare into beams or view directly with optical instruments. Statement 1051 Avertissement : Les fibres ou les connecteurs déconnectés peuvent émettre des rayonnements laser invisibles. Ne fixez pas les rayons ou ne les regardez pas directement avec des instruments optiques. Énoncé 1051

The switch has two console ports: a USB micro-Type B port and an RJ-45 console port, both on the front panel.

The USB console port uses a USB Type B to 5-pin mini-Type B cable, shown in the following illustration. The USB micro Type A-to-USB mini-Type B cable is not supplied.

Note	When running Linux, access the USB Console using Minicom instead of Screen .

The RJ-45 console port uses an 8-pin RJ-45 connector. The supplied RJ-45-to-DB-9 adapter cable is used to connect the console port of the switch to a console PC.

The alarm port uses an RJ-45 connector.

See the sections Alarms and Alarm Ratings for more information.

Each port must match the wave-length specifications on each end of the cable, and for reliable communications, the cable must not exceed the allowable length

For more information about SFP/SFP+ modules and cables, see Transceiver Modules on Cisco.com.

The console port uses an 8-pin RJ-45 connector. If you did not order a console cable, you must provide an RJ-45-to-DB-9 adapter cable to connect the switch console port to a PC console port.

The following table lists the pinouts for the console port, the RJ-45-to-DB-9 adapter cable, and the console device.
