Figure 2. Cisco 7201 Ports
The Cisco 7201 includes a single Cisco 7000 Series port adapter slot, which protects existing
customer investment in interfaces and simplifies sparing. The Cisco 7201 offers scalable density
with a wide range of interfaces, including:
●
Serial and multi-channel T1/E1 and T3/E3 interfaces and Packet-over-SONET/SDH (PoS)
OC-3
●
OC-3/STM-1 PoS, T3/E3 and OC-3/STM-1 ATM, and T1/E1 Inverse Multiplexing over ATM
(IMA)
●
ISDN Primary Rate Interface (PRI), Basic Rate Interface (BRI), and High-Speed Serial
Interface (HSSI)
●
Support for hardware encryption and Layer 3 compression (VPN accelerator modules)
Memory
●
SDRAM – The Cisco 7201 ships with default memory of 1-GB SDRAM, extensible to 2-GB
SDRAM. There is only one memory slot. The memory on the Cisco 7201 is double data-
rate (DDR) memory, which provides high-performance memory access rates. Note: The
Cisco 7301 SDRAM memory module is not compatible with the Cisco 7201 SDRAM
memory module.
●
Compact Flash memory – The 256-MB Compact Flash memory used on the Cisco 7201 is
the same Compact Flash memory used with the Cisco 7200, Cisco 7401, and Cisco 7300
Series routers.
●
2-MB NVRAM – NVRAM provides sufficient room for large configurations such as
broadband or MPLS deployments.
●
1-MB Layer 2 cache – This cache provides more room for storing cached information and
allows faster CPU instruction processing.
●
64-MB boot flash memory – The 64-MB internal flash memory is large enough to hold
multiple boot helper images, crash files, Cisco IOS Software images, logging files, etc.
●
USB port – The USB Flash feature provides an optional secondary storage capability.
Images, configurations, or other files can be copied to or from the Cisco USB Flash
memory with the same reliability as storing and retrieving files using the Compact Flash
card. Cisco USB Flash memory is available in 64-, 128-, and 256-MB sizes.
