Chapter 3 Hardware Overview

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 interfaceConnection speed: 1 Gigabit per second (Gbps)

3.1.3.1Transceiver 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.

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.

4Close the transceiver’s latch (latch styles vary).
