2. A rear-panel tab adapter is required to fit the half-height cards in full-height slots.
Enabling Higher Power-Draw for Fusion ioDrive3 Cards
Some Fusion ioDrive3 accelerator cards such as the 5800 GB card draw 25 W by default but can achieve
higher performance when the PCIe slot is configured to provide more than 25 W for the device.
PCIe slots that can be configured to support more than 25 W power draw: All.
All slots can support the higher device power draw of 55 W (75 W maximum) when configured with the
override parameter in the IO Accelerator VSL software.
See the Cisco UCS power calculator to determine the total power draw for your exact server

The override parameter in the IO Accelerator VSL software (in the
/usr/modprove.d/iomemory-vsl.conf
more than 25 W from the PCIe slot. The parameter is enabled by device, by using the device serial
numbers.
The override parameter is a setting for the IO Accelerator VSL software by server and is not stored in

the device. When moved to a new server, the device defaults to the 25 W power limit until an external
power cable is added or the override parameter is enabled for that device in the new server.
