2 Installation
This chapter explains how to attach the SMT401 to a PMC motherboard.
2.1 Handling Instructions
• Observe the usual precautions for preventing damage to components by
electrostatic discharge. Personnel handling the board should be earthed.
• Avoid flexing the board along its length.
2.2 Setting Up 3.3V Supply
The SMT401 can supply 3.3V to a TIM site using the two plated mounting holes
next to the TIM sockets. The 3.3V can be supplied from the 3.3V pins on the PMC
connector or from an on board regulator. This selection is made via JP2 as follows
Link 3.3V supply
JP2 pin1 – JP2 pin2 3.3V from regulator
JP2 pin2 – JP2 pin3 3.3V from PMC connector
2.3 Installing a TIM onto the SMT401
Note: This operation should not be performed while the SMT401 is
powered up.
To install a TIM onto an SMT401, carry out the following procedure:
1. Place the TIM over the TIM sockets of the SMT401. Ensure
that the TIM is oriented correctly, as otherwise it will not fit
into the TIM sockets.
2. Apply sufficient but not excessive force to the TIM to push it
firmly into the TIM sockets.
3. Secure the TIM with M2.5 nylon bolts and nuts, using the two
holes next to the TIM connectors provided for this purpose. If
the TIM requires 3.3V (Sundance C6x TIM modules) the
supplied metal stand-offs and bolts should be used in place
of the nylon nuts and bolts. The 3.3V is supplied via the
plated mounting holes so it is essential that a good
connection is made between the plated mounting hole and
stand-off if the 3.3V supply is being used.
2.4 Installing the SMT401 onto a PMC carrier
Note: This operation should not be performed while the PMC carrier is
powered up.
The SMT401 must be affixed to the PMC carrier in the way shown below,
using the metal stand-offs, metal bolts and plastic washers provided:
