Removing a fan tray
WARNING!
 Take out the fan tray after the fans completely stop rotating.
 To avoid an unbalanced fan causing loud noise, do not touch the fans, even if they are not rotating.
To remove a fan tray:
1. Wear an ESD-preventive wrist strap and make sure it makes good skin contact and is well grounded.
2. Loosen the captive screw of the fan tray with a Philips screwdriver until it is fully disengaged from the
switch chassis.
3. Grasp the handle of the fan tray with one hand and pull the fan tray part way out the slot. Support the
fan tray bottom with the other hand, and pull the fan tray slowly along the guide rails out of the slot.
4. Put away the removed fan tray in an antistatic bag for future use.
Installing/removing a power supply
WARNING!
 In power redundancy mode, you can replace a power supply without powering off the switch but must strictly follow
the installation and procedures in Figure 15 and Figure 16 to avoid any bodily injury or damage to the switch.
 The switches do not support intermixing of AC and DC power supplies.
The HP 5900AF-48XG-4QSFP+ switches come with both power supply slots empty and the power filler
modules as accessories.
You can install one or two power supplies for these switches as needed. For more information about the
power supplies available for the switches, see "Hot swappable power supplies."
