3.1.2 Dual Personality Interfaces
There are four dual personality interfaces, comprising four 1000Base-T/SFP combo
ports. For each interface you can connect either to the 1000Base-T port or the SFP
slot. If an SFP transceiver is inserted in the SFP slot, the corresponding 1000Base-
T port will be disabled.
Note: Connect the 1000Base-T RJ-45 port only after the transceiver is removed from
the corresponding SFP slot.
3.1.3 SFP/SFP+ Slots
These are slots for Small Form-Factor Pluggable (SFP) or SFP+ transceivers. The
SFP is also referred to as a mini-GBIC. The SFP+ (SFP Plus) is an enhanced
version of the SFP and supports data rates of 10 Gbps. A transceiver is a single
unit that houses a transmitter and a receiver. Use a transceiver to connect a fiber-
optic cable to the Switch. The Switch does not come with transceivers. You must
use transceivers that comply with the Small Form-Factor Pluggable (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: 1 Gigabit per second (Gbps) or 10 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 transceiver (SFP or SFP+ module).
