  • Page 19: Installation

    Modular products require installation in a suitable PXI/LXI chassis. The module is designed for indoor use only. PREOPERATION CHECKS (UNPACKING) 1. Check the module for transport damage and report any damage immediately to Pickering Interfaces. Do not attempt to install the product if any damage is evident.

  • Page 20: Hardware Installation

    For a system comprising more than one chassis, turn ON the last chassis in the system followed by the penultimate, etc, and finally turn ON the external controller or chassis containing the system controller. 9. For Pickering Interfaces modular LXI installation there is no requirement to use any particular power up sequence.

    For PXI modules which are supported in one of Pickering Interfaces’ Modular LXI Chassis (such as the 60-102B and 60-103B) no module software update is required. If the module was introduced after the LXI chassis was manufactured the module may not be recognized, in this case the chassis firmware may need upgrading.
