• Multifunction LEDs for 10BaseT/100BaseTX port,
LRE switch and CPE device port status. Indications
includefull/halfduplex, 10/100Mbpsspeed, Ethernet
and LRE link status, as well as switch-level status
LEDs for system, redundant power supply (RPS),
and bandwidth utilization provide a comprehensive
and convenient visual management system.
Security and Redundancy
• Cisco UplinkFast technology ensures quick
fail-over recovery, enhancing overall network
stability and reliability.
• Support for TACACS+ authentication enables
centralized control of the switch and restricts
unauthorized users from altering the configuration.
• MAC-based, port-level security prevents
unauthorized stations from accessing the switch.
• User-selectable address learning mode simplifies
configuration and enhances security.
• Multilevel security on console access prevents
unauthorized users from altering switch
configurations.
• IEEE802.1D Spanning-Tree Protocol(STP) support
for redundant backbone connections and loop-free
networks simplifies network configuration and
improves fault tolerance.
• Support for optional Cisco 600-watt redundant AC
power system provides a backup power source for
up to four units for improved fault tolerance and
network uptime.
