Cisco Systems 15216 EDFA2 manual No Response from RS-232 Port, No Response from LAN Port

Chapter 10 Troubleshooting

Troubleshooting Typical Scenarios

F I N A L D R A F T - C I S C O C O N F I D E N T I A L

hostname:edfaboot% ffs file list

Determine which image files are present. Ensure that there is enough space on the FFS for two images and that the images are complete. The 2.0.1 image should be 1,683,299 bytes, the 2.1.0 image should be 2,021,467 bytes, and the 2.2.1 image should be 1,963,195 bytes. See the 2.3.0 Release Notes for the 2.3.0 image file size. Use the ffs file delete command to remove any unwanted files as needed. Use the network host ftp command to download new images as needed.

Step 6 At the hostname prompt, enter the following command:

hostname:edfaboot% srom cfg boot display

Check that the entries are complete and accurately reflect the image file names. Use the srom cfg boot modify command to correct the boot entries as needed.

Step 7 When the problems with the images and boot entries have been completed, enter the following command:

hostname:edfaboot% processor reset

The ONS 15216 EDFA2 should boot up properly. If not, use this procedure again to correct any remaining problems.

10.2.5 No Response from RS-232 Port

If the ONS 15216 EDFA2 does not respond when connected to the RS-232 (EIA/TIA-232) port, check that the physical connection is good, that power is supplied to the unit (POWER LED is on or flashing), that the DB-9 pinout is correct (see “PC Connection via Modem” section on page 3-14), that the port speed and communications configuration are correct (see “Serial Connection Procedure” section on page 3-7), and that any terminal server settings (if used) are correct.

10.2.6 No Response from LAN Port

If the ONS 15216 EDFA2 does not respond on the RJ-45 LAN port, check that the physical connection is good, that power is supplied to the unit (POWER LED is on or flashing), that the IP address and subnet mask are correct (RTRV-NE-GEN command from RS-232 port), and that the application (Telnet) is trying to access the correct IP address.

Check the two LAN port LEDs to be sure that there is a connection to the unit (the left Ethernet socket LED is on) and that traffic is flowing (the right Ethernet socket LED is on or flashing). If the unit is not booting correctly and is continuously resetting itself, you must us the RS-232 port to address the issue as detailed in the “Boot Up Failure” section on page 10-8.

10.2.7 LAN Port Activity LED Stays On

Release Notes 2.1.0, 2.2.1, and 2.3.0 Caveat CSCdx41604

Issue: Ethernet activity LED initialization.

Description: When powered up without an Ethernet cable, the activity light remains on.

Work Around: The Ethernet activity light works correctly when connected to the network.
