3.1.2.2 Auto-crossover
All ports are auto-crossover, that is auto-MDIX ports (Media Dependent Interface Crossover), so
you may use either a straight-through Ethernet cable or crossover Ethernet cable for all Gigabit port
connections. Auto-crossover ports automatically sense whether they need to function as crossover
or straight ports, so crossover cables can connect both computers and switches/hubs.
3.1.3 Transceiver Slots
These are slots for mini-GBIC (Gigabit Interface Converter) transceivers or 1000 Mbps Small Form-
factor Pluggable (SFP) transceivers. A transceiver is a single unit that houses a transmitter and a
receiver. The Switch does not come with transceivers. You must use transceivers that comply with
the SFP Transceiver MultiSource Agreement (MSA). See the SFF committee’s INF-8074i
specification Rev 1.0 for details.
You can change transceivers while the Switch is operating. You can use different transceivers to
connect to Ethernet switches with different types of fiber-optic or even copper cable connectors.
To avoid possible eye injury, do not look into an operating fiber-optic
module’s connectors.
• Type: SFP connection interface
• Connection speed: 1 Gigabit per second (Gbps)
3.1.3.1 Transceiver Installation
Use the following steps to install a mini-GBIC transceiver (SFP module).
1
Insert the transceiver into the slot with the exposed section of PCB board facing down.
2
Press the transceiver firmly until it clicks into place.
3
The Switch automatically detects the installed transceiver. Check the LEDs to verify that it is
functioning properly.
4
Close the transceiver’s latch (latch styles vary).
