Installation Precautions
The ETUs used in this system make extensive use of CMOS
technology that is very susceptible to static; therefore,
extreme care must be taken to avoid static discharge when
handling ETUs.
Make all switch setting changes on the ETU before inserting it
into the KSU.
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 5-1 Inserting the ETU into the KSU
.
When carrying an ETU, keep it in a conductive polyethylene
bag to prevent damage due to static electricity.
When handling an ETU, the installer must wear a grounded
wrist strap to protect the ETU from static electricity.
Figure 5-1 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.
