Wall, desktop, or desk-side mountable
Support for up to three network processor modules at a time, including Ethernet, Token Ring,
serial, single-mode and multimode Fiber Distributed Data Interface (FDDI), ISDN BRI, G.703,
channelized T1/PRI, channelized T1/PRI, and ATM modules. Network processor modules can
be placed in any of the three available positions in any desired combination.
The BRI 4-port and 8-port network interface modules (NP-4B/NP-8B) are not compatible with
the Channelized T1/ISDN PRI network interface module (NP-CT1) or with the Channelized
E1/ISDN PRI network interface module ((NP-CE1).
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 can
support two FDDI network processor modules. For optimum heat dissipation, use the center slot
position for the FDDI module if one is present.
The Cisco 4500-M and Cisco 4700 support all network processor modules except the
