– One LED in the center of the power supply side to indicate the
overall switch status.
• Two universal input and redundant power supplies with AC switches
and built-in fans. The power supplies plug into internal blind-mate
connectors when installed in the chassis.
• Two fan trays, each containing two fans. Air is pulled in through the rear
intake and pushed out through the vents on the SFP media side. The fans
provide adequate cooling for the maximum switch power rating of 102
Watts.
• Three digital thermometers, capable of sensing a temperature range
from -55 °C to +125°C, in 0.5°C increments.
• A motherboard that is completely enclosed in an EMI (electromagnetic
interference) enclosure tray. The logic and chassis ground are connected
to the chassis by screws. The embedded processor can process frames
up to 1024 bytes.
• A real-time clock (RTC) with a 10-year, non customer-replaceable
battery and 56 bytes of NVRAM.
