Chapter 1: General information
•
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.
Each power supply has a separate CTP card connection to allow for
independent AC power sources. The power supplies are input-rated
at 100 to 230 volts alternating current (VAC).
Connectors and indicators
Connectors and indicators include the:
•
Initial machine load (IML) button.
