9.2 Processor Modules
This section describes how to remove and fit a CPU module.
The processors and associated circuitry are housed in self-contained modules, which
are inserted into plastic air guides attached to the motherboard. There are slots for
two processor modules on the Netra T4 motherboard. Viewed from the front of the
unit, CPU0 is located immediately to the left of the memory modules. The plastic
shroud cover and shroud are also stamped 0 and 1 to further aid identification.
Note –
Slot 0 must always contain a CPU module.
Caution – To ensure proper cooling, an unused CPU slot must be fitted with a
shroud filler panel in place of a CPU module.
Caution –
When you unpack a new CPU module from its packing carton, it is
important that you observe the following handling precautions to avoid damaging
the module. 1.) When you lift the module from the packing carton in its antistatic
bag, use both hands to support the module along its short sides. 2.) After you
remove the module from its antistatic bag, handle it only by its captive screws. Do
not touch the connectors on the bottom edge of the module, which can be easily bent
or damaged by improper handling. 3.) Do not remove the plastic cover from the
connectors until you are ready to install the module. 4.) Do not grip the module by
the heat sinks, which can shift if handled improperly. 5.) Use proper ESD grounding
techniques when handling components. Wear an antistatic wrist strap and use an
ESD-protected mat. Store ESD-sensitive components in antistatic bags before placing
them on any surface.
