Summit 300-48 Switch
Consolidated "e" Series Hardware Installation Guide 51
Power Socket
The Summit 300-48 switch automatically adjusts to the supply voltage. The power supply operates
down to 90 V.
Power Switch
The Summit 300-48 switch has a power switch. Do not turn on power to the switch until instructed in
the installation procedures.
NOTE
Summit 300-48 switchThe Summit 300-48 switch certification and safety label, and the serial
number and MAC address labels are located on the bottom of the switch.
Load Sharing Power Supplies
The PoE subsystem in the Summit 300-48 supports dual power supplies for either redundant or
load-sharing modes. Redundant mode is the default and provides hitless PoE should one of the two
power supplies fail, be removed, or powered off. Load-sharing mode allows both power supplies to
provide power to the PoE system, providing greater PoE power capacity. For load-sharing operation,
the amount of power provided to the PoE system is the sum of the power supplied by the power
supplies.
NOTE
With load-sharing, all PoE devices may experience a power hit if a power supply fails.
The Summit 300-48 supports a 600 W AC internal power supply unit (PSU). The Summit 300-48
requires a minimum software level of ExtremeWare 6.2a.1.2.
To determine the wattage of the installed PSUs when the PSUs are in redundant mode, use the
show
inline-power
command. If System maximum internal inline-power field indicates 480 W, that
means that 600 W PSUs are installed.
For further details on power supplies, see “Summit 300 Optional Features” on page 75.
