Console Connectors

Different console adapters connect different interfaces in order to connect to the console port. The following are the types of console connectors for each switch:

∙Catalyst 1900, 2820, and 2900 XL series switches each have an RJ−45 console port. You can connect to the console port using a straight−through Category 5 cable.

∙The Catalyst 3000 uses a DB−9 connector to access the console port.

∙The Catalyst 5000 line uses a Supervisor Engine. To connect a console to a Supervisor Engine I or II, use a DB−25 connection. If the switch uses a Supervisor Engine III, use the RJ−45−to−RJ−45 rollover cable.

∙The Catalyst 6000 family also uses a Supervisor Engine with an RJ−45 style connector and an RJ−45−to−RJ−45 straight−through cable.

∙The Catalyst 6500 uses a rolled cable from the console port.

You can use a number of connectors when connecting different devices using your rolled or straight−through cable:

∙To connect a PC to any console cable, attach the RJ−45−to−DB−9 female Data Terminal Equipment (DTE) adapter to one of the nine−pin serial ports on the PC.

∙To attach to a Unix workstation, use the RJ−45−to−DB−25 Data Communications Equipment (DCE) adapter (female).

∙To connect a modem to the console port, use the RJ−45−to−DB−25 (male) adapter.

Note Console port settings by default are 9600 baud, 8 data bits, 1 stop bit, and no parity.

Normally, all three connectors will come with your switch. You will need to use the appropriate adapter for the device with which you are configuring your switch.

Cisco uses two types of RJ−45−to−DB−25 connectors: the DCE style (used for modem connections) and the DTE style (used to connect to terminals or PCs).

The RJ−45−to−AUX Port Console Connector Pinouts

Most often, you will use a connection to a PC or a laptop. The connector signal appointments for each pin on the auxiliary (AUX) port DB−9 connector are shown in Table 2.4. Table 2.5 shows the connector pinouts for an RJ−45−to−DB−9 AUX port connector by color.
