Listed below are the line cards for C1400 that, together with the C1400 base unit, make up the closest equivalent model; e.g., the WS-X1431 line card plus the WS-C1400 base chassis lists for $7,995 and together form the closest comparable model to the WS-C1131-a C1100 Chassis with a 4-port FDDI line card included
