SAN140M Installation and Service Manual 8
• Four duplex LC connectors for attaching fiber-optic cables.
• An amber LED (at the top of the card) that illuminates if any port
fails or blinks if FRU beaconing is enabled.
• A bank of amber and green LEDs above the ports. One amber
LED and one green LED are associated with each port and
indicate port status as follows:
— The green LED illuminates (or blinks if there is active traffic)
and the amber LED turns off to indicate normal port
operation.
— The amber LED illuminates and the green LED turns off to
indicate a port failure.
— Both LEDs turn off to indicate a port is operational but not
communicating with an N_Port (no cable attached, loss of
light, port blocked, or link recovery in process).
— The amber LED flashes and the green LED either remains on,
turns off, or flashes to indicate a port is beaconing or running
online diagnostics.
