Note
OL-3967-01
Upgradeable boot ROM for storing sufficient code for booting the Cisco IOS software
CompactFlash Disk: Stores sufficient code for booting the Cisco IOS boot loader image (bootdisk:)
NVRAM for storing the system configuration and environmental monitoring logs. NVRAM uses a
lithium battery to maintain its contents when disconnected from power.
Non-upgradeable boot ROM provides a "golden copy" of the default ROMmon image.
Auxiliary port with full data terminal equipment (DTE) functionality
Console port with full data communications equipment (DCE) functionality
Sending and receiving routing protocol updates
Managing tables, caches, and buffers
Monitoring interface and environmental status
Providing Simple Network Management Protocol (SNMP) management
Booting and reloading images
Managing line cards (including recognition and initialization during online insertion and removal)
High availability (HA) support and management for two NSE-100s, one active and one standby
