Common procedures for installing, removing, and replacing
the PCIe3 6-slot fanout module
This section contains all the common procedures that are related to installing, removing, and replacing
parts.
Before you begin
Observe these precautions when you are installing, removing, or replacing features and parts.
About this task
These precautions are intended to create a safe environment to service your system and do not provide
steps for servicing your system. The installation, removal, and replacement procedures provide the
step-by-step processes that are required to service your system.
DANGER: When working on or around the system, observe the following precautions:
Electrical voltage and current from power, telephone, and communication cables are hazardous. To avoid
a shock hazard:
v If IBM supplied the power cord(s), connect power to this unit only with the IBM provided power cord.
Do not use the IBM provided power cord for any other product.
v Do not open or service any power supply assembly.
v Do not connect or disconnect any cables or perform installation, maintenance, or reconfiguration of this
product during an electrical storm.
v The product might be equipped with multiple power cords. To remove all hazardous voltages,
disconnect all power cords.
– For AC power, disconnect all power cords from their AC power source.
– For racks with a DC power distribution panel (PDP), disconnect the customer's DC power source to
the PDP.
v When connecting power to the product ensure all power cables are properly connected.
– For racks with AC power, connect all power cords to a properly wired and grounded electrical
outlet. Ensure that the outlet supplies proper voltage and phase rotation according to the system
rating plate.
– For racks with a DC power distribution panel (PDP), connect the customer's DC power source to
the PDP. Ensure that the proper polarity is used when attaching the DC power and DC power
return wiring.
v Connect any equipment that will be attached to this product to properly wired outlets.
v When possible, use one hand only to connect or disconnect signal cables.
v Never turn on any equipment when there is evidence of fire, water, or structural damage.
v Do not attempt to switch on power to the machine until all possible unsafe conditions are corrected.
v Assume that an electrical safety hazard is present. Perform all continuity, grounding, and power checks
specified during the subsystem installation procedures to ensure that the machine meets safety
requirements.
v Do not continue with the inspection if any unsafe conditions are present.
v Before you open the device covers, unless instructed otherwise in the installation and configuration
procedures: Disconnect the attached AC power cords, turn off the applicable circuit breakers located in
the rack power distribution panel (PDP), and disconnect any telecommunications systems, networks,
and modems.
