Removing a fan tray
WARNING!
•
Ensure electricity safety and never touch the rotating fans when you hot-swap a fan tray.
•
To prevent a fan from causing loud noise, do not touch the fan blades and rotation axis, even if
the fan is not rotating.
The removal procedure is the same for the fan trays. The following procedure removes an
LSWM1FANSA fan tray from an S6890-54HF switch.
To remove a fan tray:
1.
Wear an ESD wrist strap and make sure it makes good skin contact and is reliably grounded.
2.
Grasp the handle of the fan tray with one hand and pull the fan tray part way out of the slot.
Support the fan tray bottom with the other and pull the fan tray completely out of the slot.
3.
Put the removed fan tray in an antistatic bag.
