SECTION 2INSTALLATION
2.1 Installation Precautions
J
CMOS technology that is very susceptible to static is extensively used in
the ETUs in this system; therefore, extreme care must be taken to avoid
static discharge when handling ETUs.
J
Make all switch setting changes on the ETU before inserting it in the
KSU.
J
When installed, the component side of all ETUs must face the left side of
the KSU. Ejector tabs are always on top. Refer to Figure 6-1 Inserting
the ETU into the KSU.
J
Carry an ETU in a conductive polyethylene bag to prevent static
electricity.
J
The ETU installer must wear a grounded wrist strap to protect the ETU
from static electricity.
Figure 6-1 Inserting the ETU into the KSU
Observe the following precautions when installing the
ETUs to avoid static electricity damage to hardware or
exposure to hazardous voltages.
