3.1.3SFP Slots

The Switch comes with SFP (Small Form-factor Pluggable) 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 SFP transceiver MultiSource Agreement (MSA). See the SFF committee’s INF-8074i specification Rev 1.0 for details.

SFP transceivers can be standalone interfaces or part of a dual personality interface. Each dual personality interface has one 1000 Base-T copper RJ-45 port and one Small Form-Factor Pluggable (SFP) fiber slot for mini-GBIC transceivers, with one port active at a time. The mini-GBIC ports have priority over the Gigabit ports. This means that if a mini-GBIC port and the corresponding Gigabit port are connected at the same time, the Gigabit port will be disabled.

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 connectors.

•Type: SFP connection interface

•Connection speed: 1 Gigabit per second (Gbps)

To avoid possible eye injury, do NOT look into an operating fiber-optic module’s connectors.

3.1.3.1 Transceiver Installation

Use the following steps to install a mini-GBIC transceiver (SFP module).

1Insert the transceiver into the slot with the exposed section of PCB board facing down.

Figure 10 Transceiver Installation Example

2Press the transceiver firmly until it clicks into place.

3The Switch automatically detects the installed transceiver. Check the LEDs to verify that it is functioning properly.
