Installation guide

2.2 Installing the PIMs on the Super Card
Each Super Card carries up to three PIMs which offer a choice of physical
interface in groups of two ports. The following procedures should be
followed to initially install or change the required PIMs. They assume that
the Super Card is viewed with the circuitry uppermost and its rear panel
metalwork nearmost.
Caution: Ensure that the Super Card and PIM are suitably protected from
static discharge during these procedures. The earthing point on the rear of
the 8210/8310/8325 chassis may be used to attach suitable wrist straps etc.
To install a PIM:
1. a) Remove the jacking posts from the 25-way D-type connectors, or
b) Remove the four fixing screws from the metalwork around the 15-
way D-type connectors.
2. a) Remove the existing PIM blanking cover, or
b) Gently but firmly lever the existing PIM up so that the plastic pillars
disengage from the PIM PCB, allowing the PIM to be removed from
the socket strips on the Super Card.
3. Carefully locate the PIM, solder-side up, with its interface connectors
positioned through the holes in the Super Card metalwork.
4. Engage the header strips of the PIMs with the socket strips on the
Super Card.
5. Check that all pins are correctly located, and gently but firmly press
the PIM down so that the plastic pillars locate in the smaller holes of
the PIM PCB.
6. Secure the PIM to the Super Card rear metalwork using either the
jacking posts or fixing screws removed at stage 1.
To remove a PIM:
1. Carry out operation 1 above.
2. Carry out operation 2 b) above.
3. Replace the PIM with a PIM blanking cover (part number X890-
904503), secured with four fixing screws.
