IBM x3100 M3 4253 Installation And User Manual page 55

v Locate the documentation that comes with the adapter and follow those
instructions in addition to the instructions in this section. If you must change the
switch setting or jumper settings on the adapter, follow the instructions that come
with the adapter.
v Read the documentation that comes with your operating system.
v The server comes with the following adapter connectors or slots:
– Slot 1, PCIe2 x16 (8, 4, 1) 25W
– Slot 2, PCIe2 x8 (8, 4, 1) 25W
– Slot 3, PCIe2 x4 (4, 1) 25W
– Slot 4, PCI 32bit, 33MHz
v The server scans slot 1, slot 2, slot 3, and slot 4 to assign system resources.
Then, the server starts the PCI devices in the following order, if you have not
changed the default startup sequence: slot 1, slot 2, slot 3, and slot 4.
v The 32-bit slot 4 support 5.0 V keyed PCI adapters; they do not support 3.3 V
keyed adapters. Universal adapters are supported in slot 4 if they are universally
keyed.
v The optional ServeRAID-BR10il controller v2 enables integrated RAID levels 0
and 1.
v The server does not support full-length adapters.
v For a list of supported options for the server, see http://www.ibm.com/servers/
eserver/serverproven/compat/us/.
To install an adapter, complete the following steps.
Note: 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 you work inside the server with the power
on.
1. Read the safety information that begins on page v and "Installation guidelines"
on page 22.
2. Turn off the server and peripheral devices and disconnect all external cables
and power cords.
3. Unlock and remove the side cover. See "Removing the side cover" on page
25.
4. Lay the server on its side.
5. Follow the cabling instructions, if any, that come with the adapter. Route the
adapter cables before you install the adapter.
6. Follow the instructions that come with the adapter to set jumpers or switches, if
any.
7. Remove the screw that secures the expansion-slot cover to the chassis. Store
the expansion-slot cover and screw in a safe place for future use.
Note: Expansion-slot covers must be installed on all vacant slots. This
maintains the electronic emissions standards of the server and ensures proper
ventilation of server components.
