• A failed fan must be replaced within 48 hours since malfunction.
• A removed hot-swap fan must be replaced within 30 seconds after removal.
• A removed hot-swap drive must be replaced within two minutes after removal.
• A removed hot-swap power supply must be replaced within two minutes after removal.
• Every air baffle that comes with the server must be installed when the server starts (some servers might
come with more than one air baffle). Operating the server with a missing air baffle might damage the
processor.
• All processor sockets must contain either a socket cover or a processor with heat sink.
• When more than one processor is installed, fan population rules for each server must be strictly followed.
Handling static-sensitive devices
Review these guidelines before you handle static-sensitive devices to reduce the possibility of damage from
electrostatic discharge.
Attention:
Prevent exposure to static electricity, which might lead to system halt and loss of data, by
keeping static-sensitive components in their static-protective packages until installation and handling these
devices with an electrostatic-discharge wrist strap or other grounding system.
• Limit your movement to prevent building up static electricity around you.
• Take additional care when handling devices during cold weather, for heating would reduce indoor
humidity and increase static electricity.
• Always use an electrostatic-discharge wrist strap or other grounding system.
• While the device is still in its static-protective package, touch it to an unpainted metal surface on the
outside of the server for at least two seconds. This drains static electricity from the package and from your
body.
• Remove the device from the package and install it directly into the server without putting it down. If it is
necessary to put the device down, put it back into the static-protective package. Never place the device
on the server or on any metal surface.
• When handling a device, carefully hold it by the edges or the frame.
• Do not touch solder joints, pins, or exposed circuitry.
• Keep the device from others’ reach to prevent possible damages.
Adapter replacement
Adapters are in several locations in the I/O tray that is accessed from the rear of the server. You can install up
to 17 adapters in the server. The removal and installation procedures for each riser type are different and are
described in the following topics:
• PCIe adapters 1 to 4: see “Remove a PCIe adapter from slot 1 to 4” on page 92 and “Install a PCIe
adapter in slot 1 to 4” on page 99
• PCIe adapters 5 to 8 and the LOM adapter (slot 9):
– For PCIe adapters 5 to 8, see “Remove a PCIe adapter from slot 5 to 8” on page 93 and “Install a PCIe
adapter in slot 5 to 8” on page 100
– For the LOM adapter (slot 9), see “Remove a LOM adapter from slot 9” on page 95 and “Install a LOM
adapter in slot 9” on page 101
• PCIe adapters 10 to 15: see “Remove a PCIe adapter from slot 10 to 15” on page 96 and “Install a PCIe
adapter in slot 10 to 15” on page 102
