Dual-Purpose Port LEDs

The LEDs on the Cisco ME 3400G-12CS switch dual-purpose ports, as shown in Figure 1-12, show which is connected: either an RJ-45 connector or an SFP module. The Cisco ME3400G-2CS switch dual-purpose ports are similar to those shown in this section.

You can configure each dual-purpose port as either 10/100/1000 ports that use RJ-45 connectors or as SFP module ports, but not both types at the same time. The LEDs show how the port is being used—either as an RJ-45 Ethernet port or as an SFP module.

The LED colors have the same meanings as described in Table 1-3 on page 1-10.

Console Port

You can connect the switch to a PC by means of the console port and an RJ-45-to-DB-9 female cable. If you want to connect the switch console port to a terminal, you need to provide an RJ-45-to-DB-25 female DTE adapter. You can order a kit (part number ACS-DSBUASYN=) containing that adapter from Cisco. For console port and adapter pinout information, see the “Connector and Cable Specifications” section on page A-1.
