CAUTION:

S6820-4C switch has two fan tray slots. To replace failed fan trays on an operating switch, follow
these guidelines:
• If multiple fan trays fail on an operating S6820-32H or S6820-56HF switch, do not remove the fan
trays at the same time. Replace the fan trays one after another and finish replacing a fan tray
within 3 minutes.
• If a fan tray fails on an operating S6820-4C switch, replace the fan tray immediately and keep the
failed fan tray in position before replacement. If two fan trays fail, finish replacing the fan trays
within 1 minute.
