Front Panel LEDs
The front panel of the Extreme Networks 700/1200 W AC PSU provides status LEDs. Table 19 describes
the LED behavior on the front panel.
Table 19: Extreme Networks 700/1200 W AC PSU front panel LED behavior
The front panel on each Extreme Networks 700/1200 W AC PSU contains two cooling fans as shown in
Figure 87 . Airflow enters from the front vents on the Extreme Networks 700/1200 W AC PSU and exits
to the rear vents of the switch. Airflow through the Extreme Networks 700/1200 W AC PSU AC is
independent from the airflow that exists through the rest of the switch.
The AC input is located on the switch directly in back of each power supply bay. The front of the
Extreme Networks 700/1200 W AC PSU has a handle with a lever mechanism for both insertion and
removal as shown in
Figure 88 .
Power Supply Cords
Extreme Networks 700/1200 W AC PSU(s) come with both 110 V AC and 220 V AC power supply
cords. The 110 V AC power supply cord allows for a maximum DC output power of 700 W. The 220V
AC power supply cord allows for a maximum DC output power of 1200 W.
