3.2 1000/100M Auto-Sensing Ethernet
The IES-1248 has two 1000/100Mbps auto-sensing Ethernet ports. There are two factors
related to Ethernet: speed and duplex mode. In 1000/100Mbps Fast Ethernet, the speed can be
100Mbps or 1000Mbps and the duplex mode can be half duplex or full duplex. The auto-
negotiation capability makes one Ethernet port able to negotiate with a peer automatically to
obtain the connection speed and duplex mode that both ends support.
When auto-negotiation is turned on, an Ethernet port on the IES-1248 negotiates with the peer
automatically to determine the connection speed and duplex mode. If the peer Ethernet port
does not support auto-negotiation or turns off this feature, the IES-1248 determines the
connection speed by detecting the signal on the cable and using half duplex mode. When the
IES-1248’s auto-negotiation is turned off, an Ethernet port uses the pre-configured speed and
duplex mode when making a connection, thus requiring you to make sure that the settings of
the peer Ethernet port are the same in order to connect.
Use the Ethernet ports for subtending. You can daisy chain more IES-1248 or other Ethernet
switches.
Use with the following copper Ethernet cables: 1000Base-T 4-pair UTP Cat. 5, up to 100m.
"
For better performance and lower radiation noise, use shielded Ethernet
cables.
Each 1000/100M port is paired with a mini GBIC slot. The IES-1248 uses up to one
connection for each pair for a total of two possible gigabit connections (one from each of the
two pairs). The IES-1248 uses the mini GBIC transceiver whenever it has a connection.
3.2.1 Ethernet Default Settings
• Speed: Auto
• Duplex: Auto
3.3 SFP Mini GBIC Slots
The
SFP
slots can each house a mini GBIC (Gigabit Interface Converter) transceiver. A
transceiver is a single unit that houses a transmitter and a receiver. The IES-1248 does not
come with a transceiver. You must use a transceiver that complies with the Small Form-factor
Pluggable (SFP) Transceiver MultiSource Agreement (MSA). See the SFF committee’s INF-
8074i specification Rev 1.0 for details.
You can change transceivers while the IES-1248 is operating. You can use different
transceivers to connect to Ethernet switches with different types of fiber-optic connectors.
