This chapter shows you how to remove and install the following components:
■ Power Supply (see
10G Expansion Module (see
■
■ Stacking Module (see
The HP 2920 10G Expansion Modules and the HP 2920 Stacking Module are
not hop swappable. The switch must be powered off before installing or
replacing any of these modules.
The HP 2920 switches and their components are sensitive to static discharge.
Use an antistatic wrist strap and observe all static precautions when replacing
components.
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.
