Series Specifications
Design specifications for the Cisco 4000 series are as follows:
•Modular router platform.
•Flash memory capability.
•User-upgradable network processor modules, shared memory, and processor local memory.
•Hardware thermal alarm to warn of excessively high operating temperature.
•Can be rack-mounted in either a standard 19-inch rack or a telco rack.
•Can be mounted on a wall or placed on a desk or table.
•Support for up to three network processor modules at a time. Network processor modules can be placed in any of the three available positions in almost any desired combination. See the Cisco Product Catalog for complete configuration details.
The BRI four-port and eight-port network interface modules can not be used in the same 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.
The Cisco 4500-M and Cisco 4700-M can support one ATM network processor module or up to three six-port Ethernet network processor modules. The single-port Ethernet module is not supported on the Cisco 4500-M or the Cisco 4700-M.
Note The Cisco 4500-M and Cisco 4700-M support all network processor modules except the single-port Ethernet network processor module.
