Owner`s manual

You must take special precautions when inserting the KA65A module in or

removing it from the XMI card cage.

1. Do not let the module touch other modules or cables when you are

putting it in or taking it out of the XMI card cage.

2. When you swap out a module, temporarily place it in an unused XMI

slot, if one is available, or put it in an ESD box or on an ESD mat before

you install the new module.

An unused XMI slot is the best place to leave a module that is being

swapped out until it can be placed in the ESD box.

CAUTION: If you temporarily leave a module in an unused XMI slot,

be sure to remove the module before powering up the system.

If you put the module on an ESD mat, make sure the mat is on a stable,

uncluttered surface, with side 1 of the module facing up (the side with

the heat sinks). Do not put it on the top of the system cabinet. And

never slide the module across any surface. The leads on the components

are fragile and can be damaged by contact with ﬁngers or any surface.

3. Hold the XMI card cage handle while removing or inserting the module.

If it is not held in place, the handle can spring down and damage the

module.

4. When inserting the module in the card cage, grasp it as shown in

Figure 5–2, being careful not to touch any 25 mil devices, and slide

it slowly and gently into the slot.

5. Make sure that the module is seated ﬁrmly in the XMI slot and engaged

with the XMI backplane. Then lower the lever to close the connector.

6. When all new modules have been installed and oldmodules repositioned

(if necessary), note the new conﬁguration, and replace the clear door in

front of the XMI card cage.

NOTE: If you are doing a full power and packaging upgrade (H9657-CU

kit), the installation will entail changing DWMBA-A modules in the XMI

card cage to DWMBB-A modules.
