10/100/1000 Ports

The 10/100/1000 Ethernet ports on the switches use RJ-45 connectors. Figure 36 shows the pinouts.

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

SFP Module Connectors

Figure 37 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

Console Port

The switch has two console ports: a USB 5-pin mini-Type B port (see Figure 38) and an RJ-45 (RS-232) console port.

Figure 38 USB Mini-Type B Port

The USB console port uses a USB Type A to 5-pin mini-Type B cable, shown in Figure 39. 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.

Figure 39 USB Type A-to-USB 5-Pin Mini-Type B Cable

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 Port.

Alarm Port

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

SFP Module Cables

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.

Console Port Adapter Pinouts

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=).

Table 11 lists 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=).
