Table 4: Ethernet Ports

Description
Hardware features
Software features
Cables and connectors
LEDs
3—10/100/1000 Base-TX copper Ethernet ports that
support Ethernet, Fast Ethernet, or Gigabit Ethernet
ports
2—1000 Base-X-SFP fiber-optic Gigabit Ethernet ports
Auto-negotiation for copper ports
Cable crossover detection for copper ports
High-performance throughput on each port at speeds
up to 1000 Mbps
Full-duplex mode
Maximum transmission units (MTUs) of up to 1500
bytes
IP routing
802.1Q VLAN encapsulation support
MPLS encapsulation support
Copper (10/100/1000Base-TX): Unshielded twisted
pair (UTP), Category 5e or 6 cable, RJ-45 connector
Use Category 5e UTP cables for copper Ethernet ports if
the installation environment requires radiated noise
immunity <= 3 V/m, conducted noise immunity <= 3 V
Use Category 5e shielded twisted pair (STP) cables for
copper Ethernet ports if the installation environment
requires radiated noise immunity > 3 V/m, conducted
noise immunity > 3 V
SFP: For more information on optical interface support,
see Table 5 on page 11
Two rectangular LEDs on each side of the copper
Ethernet ports
Two circular LEDs above each fiber-optic Ethernet port
LED activities for both the copper and the fiber-optic
Ethernet ports are as follows:
Green is lit when
−
Link is up
− Traffic passes through the port
Green is off when
−
Link is down
−
No traffic
Yellow is lit when
−
Link is up
−
Admin-state is enabled
Yellow is off when
−
Link is down
−
Port not configured
