Figure 9. Installing Power Module in Unit
1.
Install one to four matching hot-swappable power modules — with the
same voltage rating — in any remaining open shelf positions. The
modules will share the total output load, automatically disconnecting
from the internal power bus in the event of an internal failure and may
be “hot-swapped” (can be inserted or removed while the shelf is
powered). If “N+1” redundancy is needed, ensure the combined power
rating of the installed power modules exceeds the total requirement of
the planned load by at least 700 watts (or 1500 watts if using ICT1500-
watt power modules).
NOTE: N+1 operation requires excess power module capacity to ensure
that the load can be fully powered, even if one power module should
fail or be removed.
2.
Carefully align each power module with the internal shelf guides.
3.
Firmly push into the shelf back plane until the module latch clicks, and
the module is flush with the unit’s front panel.
NOTE: The power modules can be easily removed by pressing the release
latch to the right while firmly pulling the module from the unit (the
shelf may be powered while swapping modules). The latch is located
under the module handle (see Figure 9).
4.
Install a shelf blanking plate (ICT-BPM) into any unused shelf positions
to prevent accidental access to the internal circuitry of the shelf.
