2 Servicing the System
This chapter describes how to replace the standard parts within a TDZ 2000 GL2 or
ExtremeZ GL2 system. Obey all warning and caution labels while replacing parts.
Note that internal parts servicing procedures assume you have removed the left side panel
from the system. After you have finished servicing the system, replace panels as described in
Chapter 1, “Accessing the System.”
WARNING Disconnect the system from AC power before servicing internal components! Failure
to remove AC power may result in equipment damage or personal injury.
NOTE See Chapter 1, “Accessing the System,” for instructions on opening the system and
protecting against electrostatic discharge.
CAUTION Follow all warnings and cautions in servicing instructions. If you fail to follow documented,
approved procedures, personal injury or damage to equipment can result.
CAUTION Use an antistatic wrist strap for all servicing procedures to avoid the possibility of
electrostatic discharge.
CAUTION Do not overtighten screws and other fasteners to avoid damaging threads.
