Hot-Swapping Power Supplies
OmniSwitch 6855 Series switches support hot-swapping of their power supplies. The following sections
describe how to hot-swap a power supply either directly connected (i.e., without a cable) or rack-mounted
power supply.
Warning: Before proceeding, ensure a redundant power supply is connected and operational.
Anti-Static Warning. Before handling any components, free yourself of static by wearing a grounding
strap, or by grounding yourself properly. Static discharge can damage the switch and the backup power
supply.
