3.1.3 Fast Ethernet SFP Slot
The ES-2108-F comes with a slot for 100-Base FX, 100-Base LX or 100-Base BX 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 connectors.
• Type: SFP connection interface
• Connection speed: 100 Mbps

To avoid possible eye injury, do not look into an operating fiber-optic module’s
connectors.
See Section 3.1.4.1 on page 44 and Section 3.1.4.2 on page 45 for transceiver installation and
removal instructions.
3.1.4 Mini-GBIC Slot
This is a slot 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.
There is one Gigabit Ethernet and mini-GBIC slot each. The mini-GBIC slot has priority over
the Gigabit port. This means that if the mini-GBIC slot 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)
