This chapter describes how to remove and install the following components:
• Power supply
• Stacking module
• Uplink port module
NOTE: The optional stacking module is not hot-swappable. Remove all power from the switch before
removing the stacking module. See Replacing the stacking module on page 65 for more
information.
An uplink module (JL078A, JL081A, and JL083A) is hot-swappable with another uplink module
having the same SKU. In this case, put the installed uplink module in savepower mode, swap it, and
then take it out of savepower. Uplink modules having different SKUs are not hot-swappable with
each other. In the case of uplink modules having different SKUs, you must use the flexible-
module <MODULE-NUM> remove put the uplink module in savepower mode, swap it, and then take
it out of savepower.
CAUTION: The 2930M switches and their 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.
Replacing the power supply
If a 2930M switch is configured with redundant power supplies, the switch will not suffer any loss of traffic or
performance if one power supply fails. Replace the failed component as soon as possible. The PS (Power
Supply) LED will flash simultaneously with the switch Fault LED indicating a power supply has failed.
