Chapter 3 Hardware Overview • Flow control: Off 3.1.3 Transceiver Slots These are slots for mini-GBIC (Gigabit Interface Converter) transceivers or 100Mbps SFP (Small Form-Factor Pluggable) 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. There are two pairs of Gigabit Ethernet/mini-GBIC ports. 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. The ES-3124-4F and ES-3124F also have two mini-GBIC ports for connection to other switches. The ES-3124F has 24 100Mbps SFP ports to connect to a computer or a switch. 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) 1 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 or 100Mbps SFP transceivers. 1 Insert the transceiver into the slot with the exposed section of PCB board facing down. Figure 13 Transceiver Installation Example 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. 38 ES-3124 Series User's Guide
