3.1.2.1 Default Ethernet Settings

The factory default negotiation settings for the Ethernet ports on the switch are:

• Speed: Auto

• Duplex: Auto

• Flow control: on

3.1.3 SFP 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)

Note: 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).

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