FRU Replacement
3–5
3.1.1 Before Replacing FRUs
The following criteria apply when removing or installing
DECstation FRUs.
CAUTION
After you turn power to the system off, do not disconnect
the power cord from the system unit or wall outlet for at
least 20 seconds.
•
Always turn power to the system and monitor off and
disconnect all external cables before removing any FRU.
NOTE
Before disconnecting the DECstation from a network,
inform the system administrator that you are going
to disconnect the ThinWire T-connector from the
computer. Do not disconnect any cable or terminator
from the T-connector. Doing so disrupts network
operation.
CAUTION
Always use a grounded wrist strap and grounded work
surface to earth ground when opening the system
unit or handling any external component and its
replacement. Static electricity can damage printed
circuit boards and mass storage devices.
•
After replacing a FRU, verify that it and the system function
properly.
