Combining Different AC PSU Models

Make sure that the 600/900 W AC PSU circuit is not overloaded. Use proper over-current protection, such as a circuit-breaker, to prevent over-current conditions.

Fuse

The Extreme Networks 600/900 W AC PSU line and neutral legs are both fused. Power to the system may still be live if the neutral fuse is open. This is not a field operator replaceable fuse. In the event of failure, immediately return the Extreme Networks 600/900 W AC PSU for a complete replacement.

WARNING!

Field operators must not attempt to configure or replace fuses in Extreme Networks 600/900 W AC PSUs! In the event of failure, immediately return the defective Extreme Networks 600/900 W AC PSU for a complete replacement.

Specifications

The 600/900 W AC PSU functions from 90 V to 264 V and 47 Hz to 63 Hz AC Input. Each PSU provides 600 W to the system if the AC input is in the 110 V low-line output power range and 900 W to the system if the AC input is in the 220 V high-line output power range.

A greater number of PSUs are needed to support the load if the low-line power range is used to power the switch. The software determines the maximum available power required for the switch and enables the modules accordingly.

Combining Different AC PSU Models

When 600/900 W AC PSUs and 700/1200 W AC PSUs are combined in the same BlackDiamond 8806 chassis and are powered on, all PSUs will be budgeted down to the lower powered 600/900 W AC output values to avoid PSU shutdown due to over-current. ExtremeXOS optimizes total system power, avoiding the possibility of over-current, by deciding whether to budget down PSUs with 220 V AC inputs when PSUs with 110 V AC inputs are present, or to keep 110 V AC PSUs disabled.

CAUTION

Even though this process avoids the possibility of over-current, an I/O module may be powered off if a 600/900 W AC PSU is added to a BlackDiamond 8806 system running in the following configuration:

●The system is powered by three 700/1200 W AC PSUs at 220 V AC.

●The system includes four or more PoE I/O modules with a PoE power requirement that falls between 2391 W and 2438 W of inline power.

To avoid causing an I/O module to be powered off, do not add a 600/900 W AC PSU to an existing BlackDiamond 8806 system running in the configuration listed above. Extreme Networks also recommends that you avoid mixing 220 V AC and 110 V AC inputs when both 600/900 W and 700/1200 W PSUs are present in the same system. When a combination of 220 V AC and 110 V AC inputs is applied, ExtremeXOS is designed to optimize total chassis power for each individual PSU type but not for a mixture of PSU types.
