KA52/53/54 CPU Module Description

1.3 MS44 or MS44L Memory Option Installation

The MS44 and MS44L memory options consist of four memory modules each.

Install an MS44 or MS44L memory option on the KA52/53/54 CPU module as

follows:

1. Position the KA52/53/54 CPU module, component side up, so that the edge

connectors are facing away from you.

2. Identify the connectors on the KA52/53/54 CPU module into which you

must install the memory option (see Figure 1–4 and Table 1–2).

3. Insert the ﬁrst memory module, with the side containing the bar code

facing away from you, into the connector on the KA52/53/54 CPU module

(see Figure 1–5).

Caution

The connectors are keyed to ensure that you install the memory

modules with the correct orientation. Do not force the modules into the

connectors with an incorrect orientation.

Caution

Make sure that you fully install the memory module into the connector

before you tilt the module toward the front of the enclosure.
