The amber LED blinks if FRU beaconing is enabled.
UPM Card
Each UPM card (Figure 1-4) provides four full-duplex generic ports
(G_Ports) that transmit or receive data at 2 gigabits per second
(Gbps). G_Port functionality depends on the type of cable
attachment. UPM cards use non-open fiber control (OFC) Class 1
laser transceivers that comply with Section 21 of the Code of Federal
Regulations(CFR),Subpart(J)asofthedateofmanufacture.
The card faceplate contains:
• Four duplex LC connectors for attaching fiber-optic cables.
• AnamberLED(atthetopofthecard)thatilluminatesifanyport
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 extinguishes to indicate normal port
operation.
— The amber LED illuminates andthegreenLED extinguishes to
indicate a port failure.
— Both LEDs extinguish 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,
extinguishes, or flashes to indicate a port is beaconing or
running online diagnostics.
