xStack DES-3800 Series Layer 3 Stackable Fast Ethernet Managed Switch
2
Both SFP ports support the following transceivers:
• DEM-310GT (1000BASE-LX)
• DEM-311GT (1000BASE-SX)
• DEM-314GT (1000BASE-LH)
• DEM-315GT (1000BASE-ZX)
The Switch provides two 1000 BASE-T ports on the rear panel. Both 1000BASE-T ports comply with the following standards:
• IEEE 802.3
• IEEE 802.3u
• IEEE 802.3ab
• Support Full-Duplex operations
• IEEE 802.3x Flow Control support for Full-Duplex mode
NOTE: The SFP combo ports on the Switch cannot be used simultaneously with the
corresponding 1000BASE-T ports. If both ports are in use at the same time (ex. port 25 of
the SFP and port 25 of the 1000BASE-T), the SFP ports will take priority over the combo
ports and render the 1000BASE-T ports inoperable.
Front-Panel Components
The front panel of the Switch provides twenty-four 10/100BASE-TX ports for the DES-3828, DES-3828P and DES-3828DC, and
forty-eight 10/100BASE-TX ports for the DES-3852, two 1000 Base-T/SFP combo ports, and an RS-232 console port (for the
DES-3828, DES-3828P and DES-3828DC only). The DES-3828P also includes a Mode Select button for changing the mode from
Link/Act/State to PoE.

DES-3828P LEDs
LED indicators display the status of the Switch and the network. The front panel of DES-3828P has LED indicators for power,
console, RPS, 27GE (rear port), 28 GE (rear port), Link/Act/Speed, PoE, for each of the twenty-four 10/100 Mbps Ethernet ports,
and for the two 1000BASE-T/SFP ports.
