Sfp Transceivers (Fibre Channel Ports); Port Leds - HP 316095-B21 - StorageWorks Edge Switch 2/24 Installation Manual

• Ports, causing all Fibre Channel connections to drop momentarily until the
connections automatically recover. This causes attached devices to log out and log
back in, therefore data frames lost during switch reset must be retransmitted.
A reset should only be performed if a CTP card failure is indicated. As a precaution,
the IML/RESET button is flush mounted to protect against inadvertent activation.

SFP Transceivers (Fibre Channel Ports)

The Edge Switch 2/24 provides 24 Fibre Channel ports. A single-mode or multi-mode
fiber-optic cable attaches to a port through a small form factor pluggable (SFP)
transceiver. The SFP provides a duplex LC interface, and can be detached from the
switch port for easy replacement. The following fiber-optic transceiver types are
available:
• Shortwave laser - Shortwave laser SFPs provide short-distance connections (2 to
500 meters) through 50-micron or 62.5-micron multi-mode fiber.
• Longwave laser - Longwave laser SFPs provide long-distance connections (up to
10 kilometers) through 9-micron single-mode fiber.
• Extended longwave laser - Two types of extended longwave laser transceivers
provide connections for transferring 2.125 Gbps data up to 20 kilometers or 35
kilometers through 9-micron singlemode fiber.

Port LEDs

Amber and green/blue LEDs to the left of each Fibre Channel port illuminate,
extinguish, or blink to indicate port status and port speed.
• Amber LED - illuminates if the port fails.
• Green/blue LED - illuminates green to indicate 1.0625 Gbps port operation.
• Green/blue LED - illuminates blue to indicate 2.125 Gbps port operation.
