Srx5800 Chassis - Juniper SRX5800 Hardware Manual

NOTE: The SRX5800 Services Gateway supports a redundant SCB, provided the SCB is a
SRX5K-SCBE (SCB2) running Junos OS Release 12.1X47-D15 and later, or a SRX5K-SCB3
(SCB3) running Junos OS Release 15.1X49-D10 and later.
The SRX5800 Services Gateway does not support a redundant SCB (third SCB) card if
SRX5K-SPC-4-15-320 (SPC2) is installed with SCB1 (SRX5K-SCB). If you have installed a
SPC2 on a SRX5800 Services Gateway with a redundant SCB1 card, make sure to remove
the redundant SCB1 card.
Power supplies—When powered by standard-capacity AC power supplies, a minimum of three power
supplies are required to supply power to a fully configured services gateway. All AC power supplies
share the load evenly. The addition of a fourth power supply provides full power redundancy. If one
power supply fails in a redundant configuration, the three remaining power supplies provide full power.
When powered by DC power supplies or high-capacity AC power supplies, two power supplies are
required to supply power to a fully configured services gateway. One power supply supports approximately
half of the components in the services gateway, and the other power supply supports the remaining
components. The installation of two additional power supplies provides full power redundancy. If one
or two power supplies fail, the remaining power supplies can provide full power to the services gateway.
Cooling system—The cooling system has redundant components, which are controlled by the host
subsystem. If one of the fans fails, the host subsystem increases the speed of the remaining fans to
provide sufficient cooling for the services gateway indefinitely.
