standby for no
apparent reason.
Configurations where
devices connect across
ESX channels can cause
the ESX to detect a
looped condition.
Discuss these configurations
with Cabletron Systems
Technical Support before
implementing them into your
network.
User parameters (IP
address, Device and
Module name, etc.)
are lost when the
ESX is powered
down or the front
panel RESET button
is pressed.
Position of the NVRAM

defective.
Reenter the lost parameters
as necessary.
Call Cabletron Systems
Technical Support.
