PEX startup process

PEX startup process differs depending on the availability of storage media on PEXs.
If a PEX has a storage medium, it can start up from the local medium or from the medium on the
•
parent device.
If a PEX does not have a storage medium, it must start up from the storage medium on the master

HP 5700 switches can operate as PEXs for a 10500 eIRF system.
NOTE:

on the parent devices are called remote startup images.
