3 Carefully slide the PSU all the way into an open power supply bay (see Figure 53 ) until you hear a
click.
Extreme Networks recommends that you populate the two left power supply bays before the two
right power supply bays. Refer to
Table 19 for the recommended installation sequence.
NOTE
A minimum of two Extreme Networks 325 W DC PSUs are required to run a BlackDiamond 12802 switch.
WARNING!
Do not put your hand into an open power supply bay when a power supply is not present. Empty power supply bays
require a cover plate at all times.
CAUTION
Do not slam the Extreme Networks 325 W DC PSU into the system switch backplane.
CAUTION
To prevent an electrical hazard, make sure before you install the PSU in the power supply bay that the DC power
cord is not connected to the PSU.
