Extremexos Interoperability; Power Over Ethernet (Poe) Support - Extreme Networks ReachNXT 100-8t User Manual

Overview of the ReachNXT 100-8t Port Extender
Users can connect their laptops to ports on the ReachNXT 100-8t to gain access to the network. The
ReachNXT 100-8t aggregates traffic from the connected users and sends the traffic to an uplinked
ExtremeXOS switch located elsewhere (for example, in a wiring closet).
The ReachNXT 100-8t communicates with the uplinked switch using Link Layer Discovery Protocol
(LLDP). The ReachNXT 100-8t can be powered either from an AC outlet, or from inline power supplied
by the uplinked switch over the 100/1000BASE-T connection.

ExtremeXOS Interoperability

To function, the ReachNXT 100-8t port extender must be connected to an ExtremeXOS switch. The
ReachNXT 100-8t only operates when it detects an ExtremeXOS switch connected to the uplink port
through Link Layer Discovery Protocol (LLDP). LLDP must be enabled on the ExtremeXOS switch to
which the ReachNXT 100-8t is connected.
The ReachNXT 100-8t disables its user ports if no ExtremeXOS switch is detected or if the uplink is
down. The user ports are re-enabled when the uplink port is up, and an ExtremeXOS switch is detected.
Table 1 lists the ExtremeXOS versions that support the ReachNXT 100-8t. The uplinked switch must be
running a supported ExtremeXOS version in order to establish connectivity with the ReachNXT 100-8t.

ExtremeXOS 12.2

Power over Ethernet (PoE) Support

The ReachNXT 100-8t can be powered either by AC power or by the uplinked ExtremeXOS switch
using Power over Ethernet (PoE). For information about switches and modules that support PoE, refer
to the Extreme Networks web site. (In general, model numbers that end in p indicated PoE support.)
To power the ReachNXT 100-8t using PoE, connect the 100/1000BASE-T uplink port on the ReachNXT
100-8t (port 9) to a port on the uplinked ExtremeXOS switch, and enable inline power for the port on
the uplinked switch.
NOTE
If you are using the SFP uplink port to connect the ReachNXT 100-8t to the uplinked ExtremeXOS switch, you must
power the ReachNXT 100-8t using AC power.
