Ethernet, Fast Ethernet, or Gigabit Ethernet interface options
Dual channels for local console and auxiliary ports
The console port has full data communications equipment (DCE) functionality and the auxiliary port
has full data terminal equipment (DTE) functionality.
NVRAM for storing the system configuration and environmental monitoring logs
Note
NVRAM uses lithium batteries to maintain its contents when disconnected from power.
Some I/O controllers use a static RAM (SRAM) component with an external lithium battery
to provide the same functionality as the NVRAM.
Two PC Card (PCMCIA) slots that hold Flash Disks or PC cards for storing the default Cisco IOS
software image
Flash memory for storing the boot helper image
Boot ROM for storing sufficient code for booting the Cisco IOS software
Two environmental sensors for monitoring the cooling air as it enters and leaves the chassis
