The switch also provides a predictive optics monitoring (POM)
feature that monitors operation of SFP optical transceivers. Digital
diagnostics-enabled optical transceivers report temperature, voltage
current, transceiver power, and receiver power to product firmware.
Optical transceivers also provide vendor-specific threshold values for
these parameters.
Power supply assembly
The switch contains two power supply assemblies with internal
cooling fans. These redundant, load-sharing assemblies step down
and rectify facility input power to provide 12 volts direct current
(VDC) to the control processor (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 connection to the CTP card to
allow for independent AC power sources. The power supplies are
input rated at 90 to 264 volts alternating current (VAC).
Three cooling fans integrated in each power supply (six fans total)
provide cooling for the power supplies and CTP card, as well as
redundancy for continued operation if a single fan fails. Fans are
removed and replaced as part of the integrated power supply.
