c Repeat steps a and b for the other side of the EPS-LD unit.
4 Slide the EPS-LD into a 19-inch rack and secure it using appropriate rack-mount screws.
NOTE
Extreme Networks recommends that you position the EPS-LD so that the output connectors are on the
same side as the external connector on the connecting switch. If you mount the EPS-LD with the connectors
facing in the opposite direction from the Summit switch connector, leave at least 1 U between the switch and
the EPS-LD through which to slide the power cords. Do not route the power cords around the equipment rack.
Connecting the EPS-LD to the Switch
CAUTION
Do not attach the AC power cord to the EPS-LD unit until the unit is properly grounded at the electrical
outlet and the redundant power supply cord is connected.
One end of the EPS-LD cord has a keyed connector to ensure correct alignment of the connector
(Figure 248). The key is a plastic tab on the cord connector housing that fits into the EPS-LD unit.
Figure 248: EPS-LD Connector with Key
To connect the EPS-LD to the switch:
1 Connect the keyed end of the cord to the power supply unit (see Figure 249).
2 Align and tighten the captive retaining screws on the connector.
3 Connect the other end of the EPS-LD cord to the Extreme switch.
The connector fits in only one direction.
