Serial WAN Interface Cards
Installing a Cisco Serial WAN Interface Card
Install the Cisco serial wan interface card according to the instructions in
Cards in Cisco Access
Grounding
Ensure that the equipment you are working with is properly grounded according to the instruction in
Installing Cisco Interface Cards in Cisco Access
Cables
After you install the serial WIC, use the appropriate serial cable to connect the WIC's serial port to one
of the following types of equipment. (See
•
•
The 1-port serial WIC has a DB-60 serial port, whereas the 2-port serial WIC and the 2-port A/S WIC
have Cisco smart serial ports. Use the correct cable for your serial WIC.
The serial cable attached to a smart serial port determines the port's electrical interface type and mode
(DTE or DCE).
A cable providing surge protection (CAB-SS-SURGE) is also available from Cisco Systems. See the
Tip
"For connection limitations, see the "1- and 2-Port Serial WICs" section on page 2, and the "2-Port
Asynchronous/Synchronous Serial WIC" section on page 2." section on page 5
connecting the surge protector cable.
Types of Cables for 1- and 2-Port Serial WICs
Six types of serial cables (also called serial adapter cables or serial transition cables) are available from
Cisco Systems for 1- and 2-port serial WICs:
•
•
•
•
•
•
All serial cables provide a universal plug at the interface card end. The network end of each cable
provides the physical connectors most commonly used for the interface. For example, the network end
of the EIA/TIA-232 serial cable is a DB-25 connector, the most widely used EIA/TIA-232 connector.
All serial interface types except EIA-530 are available in DTE or DCE format: DTE with a plug
connector at the network end and DCE with a receptacle at the network end. V.35 is available in either
mode with either gender at the network end. EIA-530 is available in DTE only.
