You can use unshielded twisted pair (UTP) or shielded twisted-pair (STP) Ethernet cables for RJ-45 ports.
The following table describes the types of network cable used for the different connection speeds.
3.1.1 RJ-45 Auto-negotiating Ports
The 10 Base-T/100 Base-TX/1000 Base-T RJ-45 ports are auto-negotiating and auto-crossover.
An auto-negotiating port can detect and adjust to the optimum Ethernet speed (10/100/1000 Mpbs)
and duplex mode (full duplex or half duplex) of the connected device.
An auto-crossover (auto-MDI/MDI-X) port automatically works with a straight-through or crossover
Ethernet cable.
3.1.2 IEEE 802.3az EEE
The Switch supports the IEEE 802.3az EEE (Energy Efficient Ethernet) standard to help reduce power
consumption. This allows the Switch to go into power saving mode and switch off part of receive and
transmit circuitry when it is not transmitting or receiving data through an Ethernet connection.
An EEE-enabled device initiates Low Power Idle (LPI) signals to negotiate and wake up the remote
device when there is data to be transmitted. To use EEE, both devices should be EEE compliant.
EEE is configured on a per-system basis in the Switch. If one of the networking devices that connect to
the Switch doesn't support EEE, EEE may not work in the Switch to save power.
Press the IEEE 802.3az EEE ON/OFF button on the GS1100-10HP to turn on the EEE feature. Disable it if you
don't want the network performance to be impacted due to the latency from the additional time
required for the sleep and wake transition or if the remote side doesn't support it.
Note: Only the GS1100-10HP has the IEEE 802.3az EEE button. For the GS1100-16/24E/24, the
IEEE 802.3az EEE feature is enabled by default.
3.1.3 Gigabit Ethernet Ports
The Switch has 1000Base-T auto-negotiating, auto-crossover Ethernet ports. In 10/100/1000 Mbps
Gigabit, the speed can be 10 Mbps, 100 Mbps or 1000 Mbps and the duplex mode can be half duplex
or full duplex.
An auto-negotiating port can detect and adjust to the optimum Ethernet speed (10/100/1000 Mbps)
and duplex mode (full duplex) of the connected device.
An auto-crossover (auto-MDI/MDI-X) port automatically works with a straight-through or crossover
Ethernet cable.
