ABOUT LEDS
The WEB/CP-700 provides a number of LEDs on its main board. Only the Status and Heartbeat LEDs are visible on the cover.
Checking other LEDs requires first removing the cover.
LEDs include the following types:
• Status
• Debug
For the location of LEDs on the main board, see Fig. 5, page 10.
Status
The green “STATUS” LED is located on the cover. On the main board, it is also the green “SYSOK” LED next to the “HBEAT”
LED—both are found near the Ethernet connector housing. The status LED should remain lit whenever the WEB/CP-700 is
powered, or else be blinking during the boot sequence. If the status LED does not light while power is applied, contact System
Engineering for technical support.
Heartbeat
The yellow heartbeat “HBEAT” LED is located on the cover, as well as on the main board next to the “SYSOK” Status LED. The
heartbeat LED blinks about once per second. If the heartbeat LED stays
on constantly, does not light, or blinks very fast (more
than once per second), contact your local distributor for technical support.
Debug
The yellow “DEBUG” LED is located on the main board near the Ethernet connector housing, and remains lit whenever the WEB/
CP-700 has been rebooted with the “serial mode select” jumper in the “serial shell” position (see Fig. 5, page 10). This indicates
that the DB-9 RS-232 port is operating in serial shell mode.
Ethernet Ports
Two LEDs for each of the two LAN ports are provided on the back of the metal LAN connector housing, and operate as follows.
The left-side
green “activity” LED indicates activity on that port as follows:
•
Off — No Ethernet link is made
•
On — Ethernet link is present, but no activity on the LAN
•
Blinking — Ethernet link is present with data activity on the LAN.
The right-side
yellow “speed” LED Indicates Ethernet connection speed, as either:
OFF - "Fast Ethernet"/"Ethernet" (100 Mbps/10 Mbps).
ON - "Gigabit Ethernet" speed (1000 Mbps).
MAINTAINING THE WEB/CP-700
This section provides information on the following topics:
• Cleaning
• Required NiMH Battery Maintenance
Cleaning
If dust or metal filings are present inside the unit, clean with vacuum or compressed air. Otherwise, no cleaning inside the unit is
required. If the cover becomes dirty, you can wipe it with a damp cloth and mild detergent.
