Mixing WAN DFCs
The Cisco AS5350 and Cisco AS5400 support only one type of WAN DFC at a time. The DFCs that can
be installed at one time are:
• Up to three T1 DFCs (any combination of 2, 4, or 8-port) or
• Up to three E1 DFCs (any combination of 2, 4, or 8-port) or
• One CT3 DFC or
• One CT3 DFC and up to two T1 DFCs (any combination of 2, 4, or 8-port)
The universal gateway software recognizes DFCs in the order of the slots they are in. For example, a
DFC in slot 2 will be recognized before a DFC in slot 3. The system will recognize if there is a mix of
WAN DFCs during both power up and OIR:
• During power up, the first WAN DFC recognized by the system will be the only type brought up.
• If there are two or more WAN DFCs of the same type and one is hot-swapped with another of a
different type, the new one will not be recognized.
In both situations, an error message will appear on the console that is similar to:
00:01:12:%CARRIER-2-T1_E1_MIX:Cannot mix T1 and E1 8PRI DFC cards in chassis, do not power
up invalid card in slot 7
