Checking the LEDs (Lights)
Look at the LEDs (lights) on the top panel of the P-870H/HW-51a v2.
• The POWER light blinks during start-up and is green once the P-
870H/HW-51a v2 is ready.
• Each ETHERNET light turns on if the corresponding ETHERNET
port is properly connected. The lights blink when the P-870H/HW-
51a v2 is sending or receiving data through the corresponding
ETHERNET port.
• The DSL light stays on if a physical DSL connection exists and
blinks when transmitting data.
• The INTERNET light is green when Internet access is available.
• The WLAN/WPS light stays green when the wireless LAN is ready.
It blinks when the P-870HW-51a v2 is sending/receiving data
