Upm Card Leds And Connectors - HP StorageWorks Director 2/140 Installation Manual

• If the G_Port is attached to another director to form an Interswitch Link (ISL), the port functions as
an expansion port (E_Port). A multi-switch fabric is formed through multiple directors and ISLs.

UPM card LEDs and connectors

Single-mode or multi-mode fiber-optic cables attach to UPM cards through small form factor
pluggable (SFP) optic transceivers. The fiber-optic transceivers provide duplex connectors, and can
be detached from UPM cards (through a 10-pin interface) for easy replacement. Three fiber-optic
transceiver types are available:
• Short-wave laser—Short-wave laser transceivers provide connections for transferring data over
short distances (2 to 500 meters) through 50-μm (500 meters) or 62.5-μm (200 meters)
multi-mode fiber.
NOTE: HP recommends 50-μm fiber-optic cable for any new installation requiring multi-mode fiber.
• Long-wave laser—Long-wave laser transceivers provide connections for transferring data over
long distances (up to 10 kilometers) through 9-μm single-mode fiber.
• Extended reach long-wave laser—Long-wave laser transceivers that provide connections for
transferring data over extended long distances (up to 35 kilometers) through 9-μm single-mode
fiber.
