McDATA® Sphereon 3032 and 3232 Fabric Switches Installation and Service Manual
General Information
NOTE: All of the following transceiver types can be used in either the 1 Gbps
or 2 Gbps switches, however a 1 Gbps transceiver used in a 2 Gbps switch
will limit that port to a 1 Gbps data rate.
• 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.
Cooling Fans
Four fans (each a separate FRU) provide cooling for the switch power
supplies and the control processor (CTP) card, as well as redundancy
for continued operation if a single fan fails.
Anyfan FRU can be replaced while the switch is operating.
Power Supplies
Redundant, load-sharing power supplies step down and rectify
facility input power to provide 3.3 volt direct current (VDC), 5 VDC,
and 12 VDC to the CTP card. The power supplies also provide input
filtering, overvoltage protection, and overcurrent protection. Either
power supply can be replaced while the switch is operational.
