·   SNMP and Telnet interface support delivers comprehensive in-band management, and a CLI management console provides detailed out-of-band management.

·   An embedded RMON software agent supports four RMON groups (history, statistics, alarms, and events) for enhanced traffic management, monitoring, and analysis.

·   A SPAN port can mirror traffic from one or many ports to another port for monitoring all eight RMON groups with an RMON probe or network analyzer.

·   Trivial File Transfer Protocol (TFTP) reduces the cost of administering software upgrades by downloading from a centralized location.

·   Two LEDs per port provide convenient visual indication of the port link and PoE status.

·   Crash information support enables a switch to generate a crash file for improved troubleshooting.

·   Show-interface capabilities provide information about the configuration capabilities of any interface.

Connectors and cabling

·   10BASE-T ports: RJ-45 connectors, two-pair Category 3, 4, or 5 unshielded twisted pair (UTP) cabling

·  100BASE-TX ports: RJ-45 connectors; two-pair Category 5 UTP cabling

·  1000BASE-TX ports: RJ-45 connectors; two-pair Category 5e and Category 6 UTP cabling

LED indicators

·   Link status LED: One LED per port for indicating link status

·   PoE LED: One LED per port system for PoE status indication
