Power supplies
The BigIron RX Series switches support the following power supply options:
•
BigIron RX-4: Accommodates three power supplies (AC or DC) with one required and two
redundant. It is shipped with one power supply. You must purchase one or two additional
power supplies if you want your BigIron RX-4 equipped for redundancy.
•
BigIron RX-8: Accommodates four power supplies (AC or DC) with two required and two
redundant. Because power is supplied over a common power bus, any power supply purchased
in addition to the two required will provide backup for any supply that fails. Equipping a BigIron
RX-8 with two additional power supplies provides full redundancy for both of the required
power supplies.
•
BigIron RX-16: Accommodates eight power supplies (AC or DC) with four required and four
redundant. Because power is supplied over a common power bus, any power supply purchased
in addition to the four required will provide backup for any supply that fails. Equipping a BigIron
RX-16 with four additional power supplies provides full redundancy for all of the required power
supplies.
•
BigIron RX-32: Accommodates eight power supplies (AC only at this time) with five required and
three redundant. Because power is supplied over a common power bus, any power supply
purchased in addition to the five required will provide backup for any supply that fails.
In the BigIron RX-8, BigIron RX-16 and BigIron RX-32, you install the power supplies (AC or DC) in
the slots along the bottom of the chassis. In the BigIron RX-4, the power supplies (AC or DC) are
installed in slots in the rear of the chassis.The installed power supplies provide power to all chassis
components, sharing the workload equally and reporting their status to the management module.
If the management module detects that one of these power supplies has failed or overheated, the
management module will redistribute the failed power supply’s workload to the remaining power
supplies.
