Extreme Networks™
is enhancing the fault tolerance of Summit switch configurations with
the Summit Redundant Power Supply (RPS). Managers of mission-critical
production networks can enhance the fault tolerance of any Summit
switch with the SummitRPS.
The SummitRPS provides redundant power supply support for up to two
Summit switches via an external DC power connection. All Summit
switches are equipped with a rear-panel DC power connector. Each
SummitRPS includes the necessary DC power cables to attach each Summit
switch.
Load-Balancing
The Summit switch balances the load between the DC output from its own
internal power supply and the DC input from the SummitRPS. As a
result, there is no service interruption if a power supply fails
because either one of the load-shared inputs can power the Summit
switch.
SummitRPS also increases system reliability. Load-balanced power
with the SummitRPS results in lower operating temperatures of the
Summit switch and increased power supply longevity. Overall, component
reliability and the mean time between failure increases.
Power Source Fault Tolerance
The SummitRPS contains two unique AC power supplies to deliver
redundant DC power to each of the two Summit switches. Because there
is greater likelihood of a power-source loss than a power supply
failure, SummitRPS has two AC line inputs, one for each power supply.
The first AC input delivers power to Power Supply A, which provides
DC power to the Summit switch attached to RPS Connector A. The second
AC input delivers power to Power Supply B, which provides DC power to
the Summit switch attached to RPS Connector B.
A Summit switch can now be protected from the failure of an AC
power source. Simply plug the Summit switch AC line into a circuit
breaker that is not being used by the SummitRPS AC line.
Autosensing capability
Similar to all Summit switches, the SummitRPS has autosensing power
supplies, which allow it to operate with either 110 VAC or 220 VAC
line inputs at frequencies between 50 and 60 Hz.
Environmental Sensors
SummitRPS is equipped with sensors that monitor internal temperature
and alert the network manager if the temperature exceeds 60° C. Fans
in the SummitRPS are built with a tachometer sensor for proactive
detection of a potential failure. The tachometer sensor detects a fan
failure if the rotation speed decreases by 20%. With advance notice,
network managers are better able to make repairs before a failure
occurs.
Since the SummitRPS does not have an internal SNMP agent, the
environmental sensors report status changes through a serial interface
that is part of the DC power cable between SummitRPS and the Summit
switch. The Summit switch attached to the SummitRPS reports the Summit
RPS over-temperature or fan-fail conditions via the command line
interface or SNMP traps.
System Indicators
The SummitRPS front panel includes system-level LEDs for at-a-glance
diagnostics and status. Lit green status LEDs mean the power supplies
are operating properly. If there is a power supply failure, the status
LEDs light amber.
There is also an LED that lights amber to indicate an
over-temperature condition and one that lights amber to indicate a fan
fail condition, which occurs when fan rotation speed is reduced by
20%.
