Hot-Swapping Power Supplies; Removing A Power Supply Or An Active Fan Blank - Intel SR6850HW4 - Server Platform - 0 MB RAM Product Manual

Hot-swapping Power Supplies

If your server is configured with two power supplies, you can replace a failed or failing power
supply without powering down the server.
CAUTIONS
The Intel® Server Platforms SR6850HW4 and SR6850HW4/M each support
up to two power supplies. If your server is configured with a single power
supply, you must have an active fan blank installed in the location for the
second power supply. This is necessary for proper chassis cooling. The steps
below can be used to install a power supply or an active fan blank.
Because of chassis airflow disruption, a power supply bay should never be
vacant (without a power supply or an active fan blank) for more than two
minutes when the server power is on. Exceeding five-minutes might cause
the system to exceed the maximum acceptable temperature and possibly
damage system components.
