Replacing Components
This chapter shows you how to remove and install the following components:
■ Fan tray (see page 4-2)
■ Power Supply (see page 4-3)
■ Stacking Module (see )
Hot Swapping ■ The fan tray can be hot swapped. The switch does not need to be powered
off to replace the fan tray. However, it needs to be done quickly before the
switch overheats (within 3 minutes).
■ The stacking module is not hop swappable. The switch must be powered
off before installing or replacing the module.
Caution The HP E3800 switches and its components are sensitive to static discharge.
Use an antistatic wrist strap and observe all static precautions when replacing
components.
Caution If a power supply must be removed and then reinstalled, wait at least 5 seconds
before reinstallation. Otherwise, damage to the switch may occur. The power
supply needs this time to bleed off any retained power.
