Juniper SRX5600, Руководство по оборудованию

Страница: 165 / 483

Both normal-capacity and high-capacity SRX5600 chassis with DC power supplies are zoned, meaning
that certain components are powered by specific power supplies (see Table 33 on page 167 for information
on zoning). When calculating power requirements, be sure that there is adequate power for each zone.
For an AC-powered chassis, there is one overall zone. Two AC power supplies are mandatory for high-line
power, and three AC power supplies are mandatory for low-line power.
The SRX5600 Services Gateway chassis with AC power supplies has one overall zone. Two AC power
supplies are mandatory for high-line power, and three AC power supplies are mandatory for low-line
power.
