Replacing an NCU
c) Put the module onto a grounded surface or an antistatic mat and let it cool
down.
d) As soon as the module has cooled down, place it in the original static-
protective package to avoid ESD damage to the module.
e) Put the static-protective package back into the original shipping box and
lay the box aside.
Step 6 Take the replacement module out of the shipping box.
Step 7 Remove it from the static-protective package and immediately place it onto a
grounded surface or an antistatic mat to avoid ESD damage to the module.
Step 8 Check and prepare the replacement module as follows:
a) Make sure that the module is the correct one for installation (type and
specifications). To quickly obtain this information, refer to the faceplate
markings and the labels on the board cover.
b) Inspect the module visually for damage and impurities. If necessary, use
canned, dry, oil-free compressed air to blow off any possible dust
particles. If a contact strip is loose, torn, or otherwise defective, do not
install this module. Return the module for repair.
Risk of electromagnetic disturbances!
Make sure that the EMC contact strips are not damaged before inserting the module.
Otherwise, EMC compliance cannot be achieved.
Step 9 Insert the replacement module into the empty slot as follows:
a) Hold the module by both screws, as shown in Figure 30 on p.î534, or by
the faceplate.
The slot position shown in Figure 30 on p.î534 apply to first generation
NCUs and NCU-II. NCU-S modules are equipped in slot B in slimline
shelves, while NCU-II-P modules are equipped in slots 3 and 18 in
SH9HU shelves.
