Summit Switch Models
Redundant Power Supply
Summit 300-24 switch software is responsible for managing overall power consumption to ensure that it
does not attempt to deliver more power than is available. The Summit 300-24 has sufficient power
budget to provide full 15.4 watts power on all 24 ports simultaneously.
The Extreme Networks External Power Supply 45019 (EPS-LD) is an optional external power supply
that provides redundant power for the Summit 300-24 switch. For instructions to install and connect the
EPS-LD, see "Installing or Removing an External Power Supply 45019 (EPS-LD)" on page 118.
To determine the wattage of installed power supplies when the power supplies are in 1-to-1 redundant
mode, use the
command. When the power supplies are in PoE mode, most of the
show inline-power
power is dissipated externally to the switch by way of the inside attached powered devices.
Summit 300-48 Switch
The Summit 300-48 is 2U high and provides 48 autosensing10BASE-T/100BASE-TX ports using RJ-45
connectors. The Summit 300-48 also provides four combination uplink ports implemented as either
10/100/1000BASE-T ports using RJ-45 connectors or optical ports using mini-GBICs. The optical ports
are also combination uplink ports. For further information, see "Summit 300 Automatic Failover" on
page 74.
The Summit 300-48 requires a minimum software level of ExtremeWare 6.2a.1.2.
The Summit 300-48 is shown in Figure 23 and Figure 24.
