Dimension ES-3024 Ethernet Switch
3-2 Hardware Connections
 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 ES-3024 switch. Connect the female end
to a serial port (COM1, COM2 or other COM port) of your computer.
3.2.2 Ethernet Ports
The ES-3024 has 10/100Mbps auto-negotiating, auto-crossover Ethernet ports. In 10/100Mbps Fast Ethernet, the
speed can be 10Mbps or 100Mbps and the duplex mode can be half duplex or full duplex (100 Mbps only).
When auto-negotiation is turned on, an Ethernet port on the ES-3024 switch 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 ES-3024 switch determines the connection speed by detecting the signal on the cable and
using half duplex mode. When the ES-3024 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.
Default Ethernet Negotiation Settings
The factory default negotiation settings for the Ethernet ports on the ES-3024 switch are:
o Speed: Auto o Duplex: Auto
o Flow control: On o Link Aggregation:
Disabled
Auto-crossover
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 Ethernet 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/hubs.
3.3 Uplink Modules
LEDs in the (optional) uplink modules are described in the corresponding module manual.
3.3.1 Installing Modules
You can install one stacking module and up to two (optional) uplink modules separately to meet the needs of your
network. See your module manual for module specifications.
Modules are NOT hot swappable!
Follow these steps to install the optional modules.
Step 1. Make sure the power cord is not connected to the switch.
