Bypass Relay Function for ITP-800(-E)
ITP-800(-E) provides two copper interfaces with auto bypass relay
function in the event of sudden power loss particularly in daisy chain or
linear topology. When power failure occurs in one of the switches,
bypass relay function can activate bypassing mechanism by
interconnecting internal circuits automatically to ensure that links
between switches operate uninterruptedly and continuously.
