Chapter 3 Hardware Overview 3.1.1 Console Port For local management, you can use a computer with terminal emulation software configured to the following parameters: • VT100 • Terminal emulation • 9600 bps • No parity, 8 data bits, 1 stop bit • No flow control Connect the male 9-pin end of the console cable to the console port of the Switch. Connect the female end to a serial port (COM1, COM2 or other COM port) of your computer. 3.1.2 Ethernet Ports The Switch has 10/100 Mbps auto-negotiating, auto-crossover Ethernet ports. In 10/100 Mbps Fast Ethernet, the speed can be 10 Mbps or 100 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 Mbps) 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. The Switch has several dual-personality interfaces, (see Figure 9 on page 28 and Figure 13 on page 29), each of which consists of an RJ-45 Ethernet port and SFP slot pair. The Switch activates one connection of each RJ-45 and SFP slot pair. The SFP slots have priority over the RJ-45 ports. This means that if an RJ-45 port and the corresponding SFP slot are connected at the same time, the RJ45 port will be disabled. When auto-negotiation is turned on, a Ethernet port negotiates with the peer automatically to determine the connection speed and duplex mode. If the peer Ethernet port does not support autonegotiation or turns off this feature, the Switch determines the connection speed by detecting the signal on the cable and using half duplex mode. When the Switch's auto-negotiation is turned off, an Ethernet port uses the pre-configured speed and duplex mode when making a connection, thus requiring you to make sure that the settings of the peer Ethernet port are the same in order to connect. 3.1.2.1 Default Ethernet Negotiation Settings The factory default negotiation settings for the Gigabit ports on the Switch are: • Speed: Auto • Duplex: Auto • Flow control: Off • Link Aggregation: Disabled 30 ES3500 Series User's Guide

3.1.1
Console Port
For local management, you can use a computer with terminal emulation software configured to the
following parameters:
• VT100
Terminal emulation
9600 bps
No parity, 8 data bits, 1 stop bit
No flow control
Connect the male 9-pin end of the console cable to the console port of the Switch. Connect the
female end to a serial port (COM1, COM2 or other COM port) of your computer.
3.1.2
Ethernet Ports
The Switch has 10/100 Mbps auto-negotiating, auto-crossover Ethernet ports. In 10/100 Mbps Fast
Ethernet, the speed can be 10 Mbps or 100 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 Mbps) 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.
The Switch has several dual-personality interfaces, (see
Figure 9 on page 28
and
Figure 13 on page
29
), each of which consists of an RJ-45 Ethernet port and SFP slot pair. The Switch activates one
connection of each RJ-45 and SFP slot pair. The SFP slots have priority over the RJ-45 ports. This
means that if an RJ-45 port and the corresponding SFP slot are connected at the same time, the RJ-
45 port will be disabled.
When auto-negotiation is turned on, a Ethernet port negotiates with the peer automatically to
determine the connection speed and duplex mode. If the peer Ethernet port does not support auto-
negotiation or turns off this feature, the Switch determines the connection speed by detecting the
signal on the cable and using half duplex mode. When the Switch’s auto-negotiation is turned off,
an Ethernet port uses the pre-configured speed and duplex mode when making a connection, thus
requiring you to make sure that the settings of the peer Ethernet port are the same in order to
connect.
3.1.2.1
Default Ethernet Negotiation Settings
The factory default negotiation settings for the Gigabit ports on the Switch are:
Speed: Auto
Duplex: Auto
Flow control: Off
Link Aggregation: Disabled
