Replacing Logic Modules
To make sure you have the correct replacement module, check the name of that mod-
ule on the left side of the module handle. (The revision level is shown on the right side
of the handle.) The card-cage slots are also labeled, as shown in Figure 3–3. Each
module is keyed so that it can be locked in place only if it is in the proper slot. Trying
to force a module into the wrong slot may damage the keys.
