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

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

The following figure shows a 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

The switch has two console ports: a USB 5-pin mini-Type B port (see the following figure) and an RJ-45 (RS-232) console port.

The USB console port uses a USB Type A to 5-pin mini-Type B cable. The USB Type A-to-USB mini-Type B cable is not supplied. You can order an accessory kit that contains this cable.

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. An RJ-45-to-DB-9 adapter cable is used to connect the console port of the switch to a console PC. You need to provide a RJ-45-to-DB-25 female DTE adapter if you want to connect the switch console port to a terminal. You can order a kit (part number ACS-DSBUASYN=) containing that adapter. For console port and adapter pinout information, see Console Ports.

The alarm port uses an RJ-45 connector. See 100/1000 SFP Ports for more information. For information on alarm ratings, see Alarm Ratings.

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.

The console port uses an 8-pin RJ-45 connector. If you did not order a console cable, you need to provide an RJ-45-to-DB-9 adapter cable to connect the switch console port to a PC console port. You need to provide an RJ-45-to-DB-25 female DTE adapter if you want to connect the switch console port to a terminal. You can order an adapter (part number ACS-DSBUASYN=).

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

Note	The RJ-45-to-DB-25 female DTE adapter is not supplied with the switch. You can order this adapter from Cisco (part number ACS-DSBUASYN=).
