Troubleshooting Typical Scenarios
10.2.2 2.0.1 to 2.2.1 Upgrade Attempt
To achieve a smooth software upgrade, the ONS 15216 EDFA2 must first get upgraded from software
version v2.0.1 to v2.1.0 before being upgraded from v2.1.0 to v2.2.1.
If a unit has been upgraded directly from v2.0.1 to v2.2.1, some features of v2.2.1 may not opera te
properly. In addition, the CISCO15 user has only read write access and cannot perform administrative
commands.
To fix this, the software must be reverted back to v2.0.1 using the uninstall procedure described in the
release notes, and then all firmware and software upgrade procedures must be performed in series, from
v2.0.1 to v2.1.0 and then from v2.1.0 to v2.2.1. See the 2.1.0 and 2.2.1 Release Notes for the procedures.
10.2.3 Image File Download Incomplete
If there is insufficient space in the flash file system (FFS) during an image file download, the
ONS 15216 EDFA2 may report that the download has completed successfully even though the file is
incomplete. Follow the upgrade instructions precisely to ensure that the file downloads completely and
the file length is checked.
If a new image does not boot correctly, check its file size using the ASH ffs file list command. 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.
If the file length is incorrect, delete the file, clear FFS space, and download the image file again. See the
2.1.0, 2.2.1, and 2.3.0 Release Notes for the procedures.
10.2.4 Boot Up Failure
If the primary image fails to boot, the ONS15216 EDFA2 boots the second image. If both fail, the
ONS 15216 EDFA2 continues to try to alternately boot the images unsucce ssfully.
If this occurs, the cause could be either corrupt or incomplete images, or incorrectly addressed or named
boot entries. Follow the instructions below to correct these problems.
Note If the ONS 15216 EDFA2 firmware is not version 2.3.14 or greater and the softwa re has not been
upgraded to 2.1.0 or greater, the CISCO15 user resets to read_write access level, not re ad_write_admin,
which has full administrative control. Contact the Cisco TAC for assistance.
Step 1 Connect to the RS-232 (EIA/TIA-232) port.
Step 2 Open HyperTerminal. (HyperTerminal can be found in the Microsoft Windows Accessories menu.)
Step 3 While the dots are present in the HyperTerminal window during the reboot process, enter Ctrl C on the
keyboard.
The ONS 15216 EDFA2 should boot from the firmware image. The prompt is %.
Step 4 At the hostname prompt, enter the following command within 60 seconds of rebooting:
hostname:edfaboot% login CISCO15
hostname:edfaboot% password
Step 5 At the hostname prompt, enter the following command:
