3.1.4 1000BASE-T RJ-45 and SFP Ports
There are two combo Gigabit RJ-45 ports with shared Small Form Factor
Pluggable (SFP) transceiver slots. If an SFP transceiver is installed (refer to
the ECN330 Installation Guide or ECN320 Installation guide) in a slot and
has a valid link on the port, the associated RJ-45 port is disabled.
The 10/100/1000BASE-T RJ-45 ports support automatic MDI/MDI-X opera-
tion, so straight-through cables can be used for all network connections to
PCs or servers, or to other switches or hubs.
Note: The 10/100/1000BASE-T RJ-45 ports do not support PoE capabil-
ity.
SFP is a new specification for compact, modular transceivers that are hot
swappable. The SFP slots support 100BASE-FX and 1000BASE-SX,
1000BASE-LX, or 1000BASE-LH transceivers for fiber optic connections to
remote devices.
The ECN330 also contains one independent 1000BASE-T RJ45 port (Port
27) that operates at 10 Mbps or 100 Mbps, half or full duplex, or at 1000
Mbps, full duplex. Because all of the Gigabit RJ45 ports support automatic
MDI/MDI-X operation, straight-through cables can be used for all network
connections to PCs or servers, or to other switches or hubs.
Each single-mode fiber optic port requires 9/125 micron single-mode fiber
optic cabling with an optical connector. Each multimode fiber optic port re-
quires 50/ 125 or 62.5/125 micron multimode fiber optic cabling with an op-
tical connector.
Warning!
This ECN uses lasers to transmit signals over fiber optic cable. The lasers
are compliant with the requirements of a Class 1 Laser Product and are
inherently eye safe in normal operation. However, never look directly at a
transmission port when it is powered on.
To connect a fiber to the SFP:
1. Check that the fiber terminators are clean. Wiping them gently with a
clean tissue or cotton ball moistened with a little ethanol can clean Ca-
ble plugs. Dirty fiber terminators on fiber optic cables will impair the
