See “Console Cable” on page 55 for cable illustration and pinout details.

To connect a terminal or PC to the Switch 8800 using the console cable: 

1 Plug the DB-9 or DB-25 female plug of the console cable to the serial port of the 

PC or the terminal where the switch is to be configured.

2 Connect the RJ-45 connector of the console cable to the console port of the 

switch.

An AUX cable is used to connect the Switch 8800 to a modem in a remote dial-up 
configuration.

The AUX cable is an 8-core shielded cable. One end of the cable is an RS-232 
RJ-45 connector, which is used to plug into the switch at the AUX port. The other 
end has both a DB-9-pin connector and a DB-25 pin for connection to a 9-hole or 
25-hole serial port on the virtual modem. 

See “AUX Cable” on page 55 for cable illustration and pinout details.

To connect the AUX cable:

1 Plug the RJ-45 end of the AUX cable into the switch AUX port.

2 Connect the DB-25 or DB-9 end of the AUX cable to the serial port of the virtual 

modem.

This section describes how to connect electrical and optical cables.

The 24-port 10/100/1000BASE-T module require a RJ-45 connector and 
category-5 twisted pair cable. See “RJ-45 Connector” on page 56 for an 
illustration of the RJ-45 connector and MDI/MDI-X pinout details.

Use the following steps to connect the port:

1 Plug one end of the straight-through cable into the Ethernet RJ-45 port of the 

switch.

2 Plug the other end of the straight-through cable into the RJ-45 port of the hub or 

LAN Switch.

The following modules require fiber optic cables and the SC or LC fiber connector:

■

1-port 10GBASE-X (XENPAK) module

■

2-port 10GBASE-X (XFP) module

■

12-port 1000BASE-X (SFP) module

■

24-port 1000BASE-X (SFP) module

See “Optical Fiber Cable Connectors” on page 57 for an illustration of the LC fiber 
optic cable connector.
