IBM 7977E7U User Manual page 39

v PCI slots 2 through 5 support full-length 3.3 V signaling adapters only.
v The PCI configuration:
– Slot 1 is a PCI Express x8 slot with x4 links, PCI Express 1.0a compliant.
– Slot 2 and 3 are PCI Express x8 slots with x8 links, PCI Express 1.0a
compliant.
– Slots 4 and 5 are PCI-X 133/64 slots, PCI-X 2.0 compliant.
– Slot 6 is a PCI 33/32 slot, PCI 2.2 compliant.
Note: The ServeRAID-8k, ServeRAID-8s, and the optional ServeRAID-10is SAS
Controllers override the standard functionality of the integrated SAS/SATA
controller with RAID capabilities.
v The system scans PCI slots 1 through 6 to assign system resources. The system
then starts (boots) the system devices in the following order, if you have not
changed the default boot precedence: integrated Ethernet controller,
ServeRAID-8k SAS Controller, and then PCI, PCI-X, and PCI Express slots.
Note: To change the boot precedence for PCI and PCI-X devices, start the
Configuration/Setup Utility program and select Start Options from the main
menu. See the "Using the Configuration/Setup Utility program" on page 54 for
details about using the Configuration/Setup Utility program.
v The server uses a rotational interrupt technique to configure PCI adapters so that
you can install PCI adapters that do not support sharing of PCI interrupts.
v You can order an optional IBM ServeRAID-MR10is VAULT SAS/SATA Controller
that supports RAID levels 0, 1, 5, 6, 10, 50, and 60. You can install the
ServeRAID-MR10is SAS/SATA controller only in server models with eight 3.5 inch
hot-swap hard disk drives installed.
Note: Note: The onboard RAID controller will be disabled by BIOS when the
ServeRAID-MR10is SAS/SATA controller is installed in the server.
Attention: Static electricity that is released to internal server components when
the server is powered-on might cause the server to stop, which might result in the
loss of data. To avoid this potential problem, always use an electrostatic-discharge
wrist strap or other grounding system when working inside the server with the
power on.
To install an adapter, complete the following steps:
1. Read the safety information that begins on page v and "Installation guidelines"
on page 21.
2. Turn off the server and peripheral devices, and disconnect the power cords and
all external cables. Remove the left-side cover.
3. See the documentation that comes with the adapter for any cabling instructions
and information about jumper or switch settings. (It might be easier for you to
route cables before you install the adapter.)
4. Open the front and rear adapter retention clips.
5. Remove the expansion-slot cover.
