Chapter 8: Emergency recovery trees
An Emergency Recovery Tree (ERT) is designed to quickly guide you through some common failures and
solutions, by providing a quick reference for troubleshooting without procedural detail.
This chapter provides emergency recovery trees (ERTs) for the following ERS 3500 failure symptoms:
• Corruption of Flash
• Incorrect PVID
• VLAN not tagged to uplink ports
• Agent recovery
Emergency recovery trees
The following work flow shows the ERTs included in this section. Each ERT describes steps
to correct a specific issue; the ERTs are not dependant upon each other.

Corruption of flash
Corruption of the switch configuration file can sometimes occur due to power outage or
environmental reasons which make the configuration of the box corrupt and non-functional.
Initializing of the flash is one way to clear a corrupted configuration file and is required before
a Return Merchandise Authorization (RMA).
