Fpm Card - HP Surestore 64 - Director Switch Planning Manual

FPM Card

Each FPM card provides four full-duplex generic ports (G_Ports) that transmit or receive
data at 1.0625 gigabits per second (Gbps). G_Port functionality depends on the type of
cable attachment. FPM 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) as of the
date of manufacture.
Depending on device connections, G_Ports behave as follows:
• If the G_Port is attached to a Fibre Channel device, the port functions as a fabric port
(F_Port). An F_Port is the interface on a director that connects to a device node port
(N_Port).
• If the G_Port is attached to a fabric element, the port functions as an expansion port
(E_Port).
Singlemode or multimode fiber-optic cables attach to FPM cards through small form factor
pluggable (SFP) optical transceivers. The transceivers provide duplex LC
can be detached from FPM cards (through a 10-pin interface) for easy replacement. Two
optical transceiver types are available:
•
Shortwave Laser
Shortwave laser transceivers provide connections for transferring data over short
distances (2 to 500 meters) through 50-micron or 62.5-micron multimode fiber.
•
Longwave Laser
Longwave laser transceivers provide connections for transferring data over long
distances (up to 10 kilometers) through 9-micron singlemode fiber.
Figure 5 illustrates the faceplate of an FPM card. The card faceplate contains:
•
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:
