100BASE-TX Network

100BASE-TX Network
When connecting a 100BASE‐TX segment to a MGBIC‐02 RJ45 port, use Category 5 UTP
cabling. The switch at the other end of the twisted pair segment must meet IEEE 802.3‐
2002 100BASE‐TX Fast Ethernet network requirements for the switches to operate at
100 Mbps.

1000BASE-T Network

The MGBIC‐02 enable you to make RJ45 copper 1000BASE‐T compliant connections.
When connecting a 1000BASE‐T segment to an MGBIC‐02 RJ45 connector, use Category 5
UTP cabling or better (Category 5e is recommended for new cable installations). The
device at the other end of the twisted pair segment must meet IEEE 802.3‐2002
1000BASE‐T Gigabit Ethernet network requirements for the devices to operate at
10/100/1000 Mbps.

1000BASE-FX Network

The Mini‐GBIC port sockets on the C2G170‐24 enable you to vary the type of 1‐Gbps port
connection. The device at the other end segment must meet the same Gigabit Ethernet
requirements for the connected devices to operate at 1‐Gigabit speed. At the time of
printing, there were five Mini‐GBICs available that support fiber‐optic connections, as
listed below:
• MGBIC‐LC01 for a 1000BASE‐SX compliant LC fiber‐optic multimode connection
• MGBIC‐LC03 for a 1000BASE‐SX standard LC duplex style connector multimode
connection
• MGBIC‐LC09 for a 1000BASE‐LX compliant LC fiber‐optic single‐mode connection
• MGBIC‐MT01 for a 1000BASE‐SX compliant MT‐RJ fiber‐optic single‐mode
connection
• MGBIC‐08 for a 1000BASE‐ELX compliant LC fiber‐optic single‐mode connection
2-2 Network Requirements
Note: When using the fixed ports on the switch for 100 Mbps operation use Category 5
UTP cabling with an impedance between 85 and 111 ohms for 100 Mbps operation.
The MGBIC-02 is capable of operating at 10, 100, or 1000 Mbps. This is accomplished by
the switch when Auto-Negotiation is enabled. This enables the switch to automatically
sense the transmission speed of the other device and adjust for the speed accordingly.
