• Duplex: Auto
• Flow control: Off
• Link Aggregation: Disabled
3.1.1.2 Auto - c ro sso ve r
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 or hubs.
3.1.2 Po E
The Switch supports the IEEE 802.3af Power over Ethernet (PoE), IEEE 802.3at Power over Ethernet (PoE)
plus and IEEE 802.3bt standards. The Switch is a Power Sourcing Equipment (PSE) because it provides a
source of power via its Ethernet ports. Each device that receives power through an Ethernet port is a
Powered Device (PD).
3.1.3 SFP Slo ts
These are slots for 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 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 or even copper cable connectors.
