3.2.1.2 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.
3.2.2 Mini-GBIC Slots
These are slots for mini-GBIC (Gigabit Interface Converter) 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
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 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)
3.2.2.1 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).
