The SafeLINC FPII contains 3 LEDs to provide user status indication. (See Figure 1 for location
of LEDs.) LED 3, colored yellow, provides trouble status information using blink codes. The
summary of the blink codes (trouble codes) appears in Table 3 below.
LEDs 1 and 2 are used to monitor both the integrity of the network connection (Link Status, Green
LED = LED1) and whether network activity is present (Network Activity, Red LED = LED2) to
and from the SafeLINC FPII.

Rest between multiple troubles = 2 seconds
Rest between repeating trouble list = 3 seconds.
Network Down (Network Status Check) - Used as a diagnostic to determine if the SafeLINC
FPII can see out onto the connected network, the SafeLINC FPII periodically checks the
customer’s configured gateway (as was configured on the boot prompt) to verify that the
SafeLINC FPII can see the gateway. However, it does not guarantee that the SafeLINC FPII is
fully operational on the network to which it is connected. The frequency of this check is
determined by configuring the Network Status Check under Administration: Security Settings.
Network Disconnected (Network Link Integrity) - The SafeLINC FPII examines the Link
Integrity Bit on the PHY to determine if the Ethernet Cable is plugged into the SafeLINC FPII. If
the cable is plugged into both the Hub/Router/Switch and the SafeLINC FPII, the Green Link
LED (LED1) will light up. There is no configurable option on the web pages for this diagnostic
feature. The SafeLINC FPII checks this at the same interval as configured for Network Down
(Network Status Check Trouble).
Internal Local Loop-Back - Testing the integrity of the onboard connection from the
microprocessor to the Ethernet Connector, the SafeLINC FPII takes an outgoing test packet and
re-routes it internally to the PHY and then back to the microprocessor. This test determines if the
PHY & MAC are operational. Between this test and the Network Disconnected Test (Network
Link Integrity Test), you are reasonably sure that the SafeLINC FPII can communicate on the
network as long as it has been configured properly.
Email Link – Periodically testing for the presence of the email server to see if it is able to accept
messages, this diagnostic logs into the SMTP server and logs out without sending any email
messages. This testing interval is defined under SafeLINC FPII: SafeLINC FPII Administration:
Email Configuration as the Email Health Status Check Interval. This test also checks that the PC
on which the server is running is operational as well as checking that the SMTP server is actually
running, too. Although this test does not check that the remaining network is operational, it does
reasonably ensure that any email message can be delivered to the server successfully.
