5. Troubleshooting
1. Is the PWR (power) LED lit?
NO
• Is the power adapter the proper type of voltage and cycle frequency for the AC outlet?
• Is the power adapter properly installed in the SGPAT and in the outlet?
• If power LED blinking, may indicate incorrect or faulty power supply.
YES
• Proceed to step 2.
2. Verify config settings. The RJ45 port may auto-negotiate speed and duplex with the link partner if
enabled, otherwise it is defined by the DIP switch or CLI command. Some config settings are DIP switch
defined only. See 6-Position DIP Switch on page 11 or see 4. CLI Commands on page 25.
3. Is the L/A LED lit Amber or green?
NO
• Check the copper cables for proper connection. Check the Auto-Negotiation setting.
YES – Amber
• The SGPAT has selected half-duplex mode. If this is not the correct mode, disconnect and reconnect
the copper cable to restart the negotiation process. See Status LEDs on page 13.
• Proceed to step 4.
YES – Green
• The SGPAT has selected full-duplex mode. If this is not the correct mode, disconnect and reconnect
the copper cable to restart the negotiation process.
• Proceed to step 4.
4. Is the 100/1000 SFP LED lit?
NO
• Check the fiber cables for proper connection. See Status LEDs on page 13.
• Verify that the TX and RX cables on the SGPAT are connected to the RX and TX ports, respectively, on
the other device.
YES
• Proceed to step 5.
5. Is the 10/100/1000 LED lit?
NO
• The SGPAT is in 10 Mb/s mode. If this is not the correct speed, disconnect and reconnect the copper
cable to restart the negotiation process. See Status LEDs on page 13.
YES – Flashing Amber
• The SGPAT is in 100 Mb/s mode. If not the correct speed, disconnect and reconnect the copper cable
to re- negotiate. Check the Auto-Negotiation setting.
• Contact Tech Support; see Contact Us on page 48 below.
YES – Flashing Green
• The SGPAT is in 1000 Mb/s mode. If this is not the correct speed, disconnect and reconnect the copper
cable to re- negotiate. Check the Auto-Negotiation setting.
