Gigabit Ethernet SFP GBIC and RJ-45 Port Identification
Intra-Building Lightning Protection
Shielded cables which are grounded at both ends are required to be used on the 10/100/1000 Ethernet port in order to be in
compliance with requirement R4-11 in GR-1089-Core for a Central Office environment. This is not a requirement for customer
premise installations.
Warning
To avoid electric shock, do not connect safety extra-low voltage (SELV) circuits to telephone-network voltage
(TNV) circuits. LAN ports contain SELV circuits, and WAN ports contain TNV circuits. Some LAN and WAN ports
both use RJ-45 connectors. Use caution when connecting cables. Statement 76
To identify the RJ-45 cable type, hold the two ends of the cable next to each other so you can see the colored wires inside the ends.
The straight-through wire type has colored wires in the same sequence at both ends. In the crossover wire type, the first colored
wire at the far left is the third colored wire at the other end. The second colored wire at the far left is the sixth colored wire at the
other end.
Attach RJ-45 Ethernet cables to the appropriate connector.
Note
Both native Gigabit Ethernet ports, SFP GBIC and RJ-45, are reported as Gigabit Ethernet 0/0, Gigabit Ethernet 0/1,
and Gigabit Ethernet 0/2 in software. You must use the media-type command to select which media type you want to
use before you configure these ports. See the “Configure the Native Gigabit Ethernet Interfaces” section on page 22.
SFP GBIC Cabling and Connection Equipment
The Gigabit Ethernet
small form-factor pluggable (SFP) GBIC module
port is a 1000-Mbps optical interface in the form of an
LC-type duplex port that supports IEEE 802.3z interfaces compliant with the 1000BASEX standard. Gigabit Ethernet SFP GBIC
models GLC-SX-MM, GLC-LH-SM, and GLC-ZX-SM are supported in the Cisco 7301 router, as are a variety of Coarse
Wavelength-Division Multiplexing (CWDM) SFPs, and the Cisco 1000BASE-T (copper) SFP with an RJ-45 port. For cabling
distances, specifications, and other information, see the online
. Also
see the Coarse Wavelength- Division
Multiplexing SFP Compatibility Matrix at
1000BASE-T SFP Data Sheet.
Note
All SFP GBIC ports have LC-type connectors.
