Dimension ES-4024 Ethernet Switch
When auto-negotiation is turned on, an Ethernet port on the ES-4024 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-4024 determines the connection speed by detecting the signal on the cable and using
half duplex mode. When the ES-4024'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 Settings
The factory default negotiation settings for the Ethernet ports on the ES-4024 are:
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.

3.2 Stacking Module

LEDs in the (optional) stacking modules and module hardware installation steps are described in the corresponding
module manual.

3.3 Rear Panel

The following figure shows the rear panel of the ES-4024. The rear panel contains the slot for the stacking module
and the power receptacle. Refer to the module manual for descriptions on hardware installation.
3.3.1 Power Connector
Make sure you are using the correct power source as shown on the panel.
To connect the power to the unit, insert the female end of power cord to the power socket on the rear panel.
Connect the other end of the supplied power cord to an appropriate power outlet. Make sure that no objects
obstruct the airflow of the fans (located on the side of the unit).
