Fixed fan tray failure
The S5560X-34S-EI and S5560X-54S-EI switches each use a fixed fan tray. If the fan tray fails,
contact H3C Support.
Hot-swappable fan tray failure
WARNING!
• If both fan trays fail during switch operation, replace them within 2 minutes.
• If one fan tray fails, perform either of the following tasks:
{ If the ambient temperature is not higher than 27°C (80.6°F), replace the fan tray within 24 hours and
make sure the failed fan tray remains in position before the replacement.
{ If the ambient temperature is higher than 27°C (80.6°F), replace the fan tray immediately.
The S5560X-EI switches except the S5560X-34S-EI and S5560X-54S-EI use hot-swappable fan
trays. If a fan tray fails, see "Installing/removing a fan tray" to replace the fan tray
.
