Inserting the Module into the Base
3-4
Installation
Before using the module, you should decide whether you want to protect it
by "keying" the module's position in the I/O base. As shown in Figure 3-1,
keying is accomplished by placing the three keys provided in the right-hand
slot of the two slots occupied by the module so that they fit into the notches
on the module edge card. This prevents another I/O module from being
mistakenly inserted into the slots reserved for a communication module.
Do not insert or remove the NIM (or keys) while power is applied to the base,
since doing this may cause personal injury, alter controller memory, cause a
controller fatal error, or damage the module.
Until you disconnect power to the I/O base, hazardous voltages are present. Inserting or
removing the NIM before disconnecting power to the base could cause death or serious
injury to personnel, and/or damage to equipment; it could also alter CPU memory, cause a
CPU fatal error, or damage the NIM.
Do not insert or remove the NIM while power is applied to the base.
