LE-3xx/LE-4xx Hardware Installation & User Guide
HARDWARE DESCRIPTION
LE-427
The LE-427 has 16 1000 Mbps SFP ports and has the same 1 RU height as most of the other
devices. Status LEDs for the 1000 Mbps ports are located immediately
above each port
. The unit
status LEDs are located on the left side of the device.

LE-427 Hardware Location
1000BASE-X Uplink Ports
The LE-310, LE-311, LE-311v, and LE-327 provide 4 dedicated Gigabit Ethernet (1000BASE-X)
ports. The LE-310 provides 3 100BASE-FX/1000BASE-X uplink ports. The LE-4xx SCS provides 16
Gigabit Ethernet (1000BASE-X) ports.These ports use small form factor, pluggable (SFP) optics,
operate only in full duplex mode, and conform to the IEEE 802.3z (Gigabit Ethernet) standard.
The SFPs are hot-swappable, allowing compliant optics to be plugged in to change the external
interface of the port, thus providing a mix of possible distances and media types.
10/100BASE-TX Subscriber Ports (LE-311, LE-311v, and LE-327)
The LE-311, LE-311v, and LE-327 devices include 24 10/100BASE-TX, autonegotiating, auto MDIX
ports for connecting subscriber and other downstream equipment. These ports use RJ-45
connectors and are fully compliant with the IEEE 802.3u Fast Ethernet standard.
Local Management Port
LE-4xx SCS devices provide one 10/100BASE-TX, autonegotiating, auto MDIX port for out-of-band
management. This port uses an RJ-45 connector and is fully compliant with the IEEE 802.3u Fast
Ethernet standard. The management port can be used to attach a PC directly to the LE-4xx SCS
or it can be plugged into a network for management. This port also contains its own status LEDs.
