McDATA Sphereon 4300 Fabric Switch Installation and Service Manual

General Information

SFP Transceiver Singlemode or multimode fiber-optic cables attach to switch ports

through SFP transceivers. The fiber-optic transceivers provide duplex

connectors, and can be detached from switch ports (through a

10-pin interface) for easy replacement. The following fiber-optic

transceiver types are available:

• Shortwave laser (1.0625 Gbps) - Shortwave laser transceivers

provide connections for transferring 1.0625 Gbps data over short

distances as follows:

— Up to 500 meters through 50-micron multimode fiber.

— Up to 300 meters through 62.5-micron multimode fiber.

• Shortwave laser (2.125 Gbps) - Shortwave laser transceivers

provide connections for transferring 2.125 Gbps data over short

distances as follows:

— Up to 300 meters through 50-micron multimode fiber.

— Up to 150 meters through 62.5-micron multimode fiber.

• Longwave laser (1.0625 Gbps) - Longwave laser transceivers

provide connections for transferring 1.0625 Gbps data up to 10

kilometers through 9-micron singlemode fiber.

• Longwave laser (2.125 Gbps) - Longwave laser transceivers

provide connections for transferring 2.125 Gbps data up to 10

kilometers through 9-micron singlemode fiber.

• Extended longwave laser (2.125 Gbps) - 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.

Power Supply

The switch contains one power supply with two internal cooling fans.

The assembly is not a FRU. The power supply steps down and

rectifies facility input power to provide 3.3 volts direct current (VDC),

5 VDC, and 12 VDC to the control processor (CTP) card. The power

supply also provides input filtering, overvoltage protection, and

overcurrent protection, and is input rated at 100 to 240 volts

alternating current (VAC).

Three cooling fans (two integrated in the power supply) provide

cooling for the power supply and CTP card, as well as redundancy

for continued operation if a single fan fails.
