Power Supplies for the E4G-400
The E4G-400 router is compatible with the following power supplies:
● 300W AC power supply (model number 10930A)
● 300W DC power supply (model number 10934A)
● 300W DC Power supply (model number 10933)
An E4G-400 router accommodates one or two 300 W power supplies. You can combine AC and DC
power supplies in the same E4G-400 router. In a redundant power configuration, both power supplies
are fully fault-tolerant and load-sharing. You can remove one power supply without interrupting
router operation.
NOTE
An AC power input cord is not provided with a 300 W AC power supply. You can order an appropriate cord
from Extreme Networks or from your local supplier. The power cord must meet the requirements listed in “Power
Supplies for the E4G-400 Router” on page 123.

The 300 W DC power supply (models 10934A and 10933) has the status LEDs listed in Table 7.
