    AT8402 Installation AT8402 Initial Installation Procedures The following procedures are applicable only for the initial installation of the AT8402 in a sys- tem. Procedures for standard removal and hot swap operations are found in their respective chapters. To perform an initial installation of the AT8402 in a system proceed as follows: Ensure that the safety requirements indicated in section 2.1.

  • Page 29: Standard Removal Procedures

    Ensure that the safety requirements indicated in section 2.1. are observed. Warning! Care must be taken when applying the procedures below to ensure that neither the AT8402 nor system boards are physically damaged by the application of these procedures. Unscrew the front panel retaining screws.
