Displaying the Status of Installed Power Supplies
Many Extreme Networks switches are shipped with an internal power supply that supplies all of the
power needed for most switch operation. The internal power supply is fixed on some models and
replaceable on other models. (See Replaceable Internal Power Supplies on page 104.)
Other switches, such as the X450-G2 and the X460-G2, require power supplies to be ordered
separately.
An optional redundant power supply can be added to most models to protect against a power supply
failure and to provide increased support for PoE operation on applicable switches.
The following Extreme Networks switches use external power supplies for redundancy:
•
X440-G2
•
X450-G2 (non-PoE models)
•
X620-8t-2x and X620-10x models
V300 Virtual Port Extender high temperature (HT) models use an external power supply for
redundancy.
The V400 Virtual Port Extender also uses an external power supply for redundancy.
The following switches provide power redundancy by installing a second replaceable power supply:
•
X450-G2 (PoE models)
•
X460-G2
•
X620 (16-port models)
•
X670-G2
•
X770
