4.2 Ethernet Port
The pin assignments in the PoE 10/100/1000BASE-T/TX Ethernet port follow the TIA/EIA-568-B standard (see Figure 3-3 and
Table 3-2). The port accepts standard types of Ethernet cable—CAT3, CAT5, CAT5e, or CAT6—and can receive power over the
Ethernet cable from PSE that is 802.3af compatible. If you use CAT5, CAT5e, or CAT6 cables, the ETH0 port can also support
802.3at-compliant PSE. Such equipment can be embedded in a switch or router, or it can come from purpose-built devices that
inject power into the Ethernet line en route to the SmartPath AP. Because the PoE port has autosensing capabilities, the wiring
termination in the Ethernet cable can be either straight-through or cross-over.
4.3 Status Indicator
The status indicator has been incorporated into the Black Box logo on the top of the SmartPath AP LWN602A. It is illuminated by
various colors to indicate different states of activity. The meanings of the colors are as follows:
• Dark: There is no power or the status indicator is disabled.
• Blue: solid: The device is booting up or there is no backhaul link; flashing: the device is shutting down.
• Green: The default route is through the backhaul Ethernet interface, but not all conditions for normal operations (white) have
been met.

Description
The status indicator conveys operational states for system power, firmware updates, Ethernet and wireless inter-
face activity, and major alarms. For details, see Section 4.3, Status Indicator.
You can physically secure the SmartPath AP by attaching a Kensington lock and cable to the device lock slot. For
more information, see Locking the SmartPath AP in Section 4.5.1, Ceiling Mount.
The reset button allows you to reboot the device or reset the SmartPath AP to its factory default settings. Insert a
paper clip, or something similar, into the Reset pinhole and press the reset button. To reboot the device, hold the
button down between 1 and 5 seconds. To return the configuration to the factory default settings, hold it down
for at least 5 seconds. After releasing the button, the status indicator goes dark as the system reboots. Then it
glows blue while the device boots and the system performs a self-test. After the firmware finishes loading and
the SmartPath AP is ready to serve clients, the status indicator glows white.
To disable the reset button from resetting the configuration, enter this command: no reset-button reset-config-
enable. Pressing the button between 1 and 5 seconds will still reboot the SmartPath AP, but pressing it for more
than 5 seconds will not reset its configuration.
The 10-/100-/1000-Mbps Ethernet port—ETH0—receives an RJ-45 connector. The SmartPath AP can receive
power through an Ethernet connection to the ETH0 port from power sourcing equipment (PSE) that is compatible
with the 802.3af standard and the forthcoming 802.3at standard. Black Box provides suitable PoE injectors as an
optional accessory. (If you connect the SmartPath AP to a power source through the power connector and the
ETH0 PoE port simultaneously, the device draws power through the power connector and automatically disables
PoE.)
The ETH0 port is compatible with 10/100/1000BASE-T/TX and automatically negotiates half- and full-duplex
connections with the connecting device. It is autosensing and adjusts to straight-through and cross-over Ethernet
cables automatically. For details, see Section 4.2, Ethernet Port.
The 48-volt DC power connector (0.3 amps), with a voltage range of 36 to 57 volts DC, is one of two methods
through which you can power the SmartPath AP (the other is PoE). To connect it to a 100 – 240-volt AC power
source, use the AC/DC power adapter that is available as an extra accessory. Because the SmartPath AP does not
have an on/off switch, connecting it to a power source automatically powers on the device.
