Nytro MegaRAID SAS Hardware Installation
RAID Cache Protection Kit (Optional)
7. Install the SAS devices, SATA devices, or both in the host server case.
Refer to the documentation for the devices for any pre-installation configuration requirements.
8. Connect the RAID card to the devices.
Use SAS cables to connect SAS devices, SATA devices, or both to the Nytro MegaRAID card. See Section 2.7, SAS
Device Cables and Connectors, for information about connecting the card to drives.
System throughput problems can occur if the SAS cables are not the correct type.
9. Turn on the power to the server.
Reinstall the server cover, and reconnect the AC power cords. Turn power on to the host server. Make sure that the
power is turned on to the SAS devices, SATA devices, or both before or at the same time that the power is turned
on to the host server. If the computer is powered up before these devices, the devices might not be recognized.
During boot, a BIOS message appears. The firmware takes several seconds to initialize. The configuration utility
prompt times out after several seconds. The second portion of the BIOS message shows the Nytro MegaRAID card
number, firmware version, and cache SDRAM size. The numbering of the cards follows the PCI slot scanning order
used by the host motherboard.
10. Run the WebBIOS Configuration Utility.
Run the WebBIOS Configuration Utility to configure the drive groups and the virtual drives. When the message
Press CTRL+H for WebBIOS appears on the screen, immediately press CTRL+H to run the utility.
11. Install the operating system driver.
Nytro MegaRAID cards can operate under various operating systems. To operate under these operating systems,
you must install the software drivers. The Nytro MegaRAID Device Driver Installation User Guide provides
information on how to install and use the drivers. Be sure to use the latest service packs provided by the
operating system manufacturer and to review the readme file that accompanies the driver.
2.6 RAID Cache Protection Kit (Optional)
The RAID Cache Protection Kit NMR-SCM01 contains a RAID Cache Protection module and a mounding bracket. The
RAID Cache Protection module contains a super-capacitor that supplies enough power to offload the DRAM cache
data in the event of a power failure. Below is a picture of the RAID Cache Protection module that plugs into the Nytro
MegaRAID card at connector J3. For details on the location of J3 connector, see Figure 7, Nytro MegaRAID Card Layout.

CAUTION DO NOT Hot Plug the SuperCap when there is power to the card or when there is existing charge
on the SuperCap, doing so my cause damage to both the card and the SuperCap.
