chassis with the channelized T1/ISDN PRI network interface module or the channelized
E1/ISDN PRI network interface module.
The Cisco 4000-M does not support Fast Ethernet, HSSI, 2T16S, ATM, or six-port Ethernet
network processor modules.The Cisco 4000-M can support only one FDDI network
processor module in combination with any two other types of network processor modules.
The Cisco 4500-M and Cisco 4700-M can support two FDDI network processor modules.
If you are only using one FDDI module, install it in the center slot for optimum heat
dissipation.
