HP e-CommerceXML Accelerator sa7150 - Manual (Page 169)

A P P E N D I X B Fail-through Switch (Security Level)
159
During normal processing, the Inline (green) LED on the front panel
indicates whether e-Commerce traffic will pass through in the event
of a failure (depending on Fail-through switch state). Steady green or
blinking green both mean that the SA7150 is processing traffic;
blinking green indicates traffic will be blocked if the SA7150 fails
(Fail-safe mode), and steady green indicates traffic will continue
(unprocessed) in the event of a failure (Fail-through mode). When the
Inline LED is off, no SSL processing is taking place, which means
either no traffic is passing through (Fail-safe), or the traffic that is
passing through is unprocessed (Fail-through).
The following conditions and Inline LED behavior are possible with
the Fail-through switch and bypass button:
