Installing/removing fan trays
CAUTION:
The switch has multiple fan tray slots. To ensure good ventilation of the switch, follow these
guidelines to install and remove fan trays:
• The switch is provided with the fan tray slots empty. Before powering on the switch, make sure all
fan tray slots have fan trays installed and the fan trays are the same model.
• Make sure all slots have a module or filler panel installed when the switch is operating.
• If multiple fan trays fail on an operating S6850-56HF, S6850-2C, or S9850-32H 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 S9850-4C 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.
The installation and removal procedures are the same for the LSWM1FANSA, LSWM1FANSAB,
LSWM1BFANSC, and LSWM1BFANSCB fan trays. The following installation and removal
procedures use the LSWM1FANSA fan tray as an example.
Installing a fan tray
CAUTION:
To prevent damage to the fan tray or the connectors on the backplane, insert the fan tray gently. If
you encounter a hard resistance while inserting the fan tray, pull out the fan tray and insert it again.
