EPS-160 External Power Module (with EPS-T)
The EPS-160 External Power Module (Model 10907) is a modular power supply for use with the EPS-T
chassis. You can use the EPS-160 as a redundant power supply with the following Extreme Networks
switches:
● Summit X150-24t switch
● Summit X150-24x switch
● Summit X150-48t switch
● Summit X250e-24t switch
● Summit X250e-24x switch

The EPS-T is a rack-mountable chassis or tray that holds one or two EPS-160 power supplies. Each EPS-
160 power supply provides one-to-one redundancy for an attached Extreme Networks switch.
You can order the EPS-T chassis with one or two EPS-160 power supplies already installed. You can also
order an additional power supply from your Extreme Networks reseller.
NOTE
Each EPS-160 power supply is shipped with a special redundant power supply cord (Figure 64). An AC power input
cord is not provided; you can order an appropriate cord from Extreme Networks or from your local supplier. The
power cord must meet the requirements listed in “Selecting Power Supply Cords” on page 218.
