10/100/1000 Ethernet Ports
Depending on the model, the S3500 is equipped with 24 or 48 10/100/1000BASE-T Gigabit Ethernet (RJ-45)
ports. Gigabit Ethernet uses all eight wires and each pair is used in a bi-directional fashion, meaning the
same pairs are used for both data transmission and reception.
Figure 3
illustrates the CAT-5 pin-out found
on an RJ-45 connector. The CAT-5 pin-out pairs the following pins on a 10/100/1000Base-T Gigabit Ethernet
port: 1/2, 3/6, 4/5, and 7/8. These ports support IEEE 802.3af Power over Ethernet (PoE), providing up to
15.4 W of DC power, as a power sourcing equipment (PSE) device, to connected devices. Additionally, the
ports can be configured to provide IEEE 802.3at Power over Ethernet Plus (PoE+), supplying up to 30.0 W
of DC power to connected devices.
For more information on PoE and S3500 Power Supplies, see
“Power Supply” on page 19

Port LEDs
Each 10/100/1000 Ethernet port is equipped two LEDs that allow you to monitor the status of and activity on
the port. These LEDs provide basic monitoring of the status, activity, and basic configuration of each port.
The information displayed by these LEDs can be changed via the LCD.
LINK/ACT
: on the left side of the port, displays the link status of the port.
Status
: on the right side of the port, displays the status of the port. The information displayed by this
LED changes based on LCD’s mode. The LED behavior for each mode is describe in
