Front Panel Leds; Rear Panel Connectors And Leds - Philips IntelliVue Telemetry System Infrastructure Installation And Service Manual

Chapter 1: Overview
The following status LEDs are provided on the APC front panel:
Front Panel
LEDs
• Power LED - The Power LED is a multi-color LED that indicates the following
status:
-
-
-
• Network Utilization LEDs - These LEDs provide indication (as a percentage) of
the amount of network traffic between the APC and the Access Points. When the
LED on the far left is ON but the rest are OFF, the network utilization is low, less
than 20%. As the amount of traffic increases, more LEDs will turn ON to indicate
an increase in the percentage of network utilization. When all six LEDs are ON,
the network utilization is greater than 90% of the AP Controller's total capacity.
The utilization value is updated ten times per second. In addition, the LEDs
indicate the peak utilization for the previous three seconds by illuminating the
LED that corresponds to that utilization percentage. For example, you may
notice that all six LEDs turn ON momentarily and then the fourth and fifth turn
OFF while the sixth remains ON. The sixth LED is ON to indicate peak utilization
reached 90% within the last three seconds.
The following connectors and status LEDs are provided on the APC rear panel:

Connectors and
• Power Receptacle - Connect the APC an AC power source that provides 100 -
LEDs
240 VAC, 1.5A max, at 50/60Hz.
• Serial Port - Use the APC serial port to connect your service PC to the APC
command line interface (CLI) to complete basic initial configuration the APC.
• Ethernet Port - The APC provides a 100 Base-T Ethernet interface with an RJ-45
connector to connect the APC to an available port on the ICN network switch.
• 100 Base-T LINK LED - Illuminates GREEN continuously when the APC has
established a 100 Mbps (NORMAL) connection. The LED is OFF when the APC
has established a 10 Mbps connection.
• LINK/ACT LED - This LED reflects link integrity as well as activity. When the
Ethernet LAN cable is physically connected to the Ethernet LAN (RJ-45
receptacle), the LED will illuminate YELLOW. When the cable is attached the
LED will remain ON/lit, and when there is activity, at which time the LED will
blink OFF momentarily. If there is a problem with the link, then the LED will
remain OFF (although the LED will blink ON momentarily when the unit attempts
to send data through its Ethernet port). A problem with an Ethernet link is
typically due to a damaged or improper Ethernet cable, or to a damaged port on
one of the linked devices.

AMBER - During initialization, the Power LED is illuminated AMBER.
GREEN - During normal operation, it is illuminated GREEN continuously.
RED - If there is an internal problem with the APC, the Power LED will
illuminate RED. If the Power LED is lit RED, try recycling power to the APC. If it
remains lit RED, then the APC will need to be replaced
