Table 26: MX480 DC Zoning

Zone
Zone 0
Zone 1
270
Both normal-capacity and high-capacity MX480 chassis with DC power supplies are
zoned, meaning that certain components are powered by specific power supplies (see
Table 26 on page 270 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, and three AC power supplies are mandatory for low-line power.
Power Supply (PEM)
PEM 0 or 2
PEM 1 or 3
The following sample configuration shows a DC-powered MX480 with:
Two 16-port 10-Gigabit Ethernet MPCs with SFP+(slots 0 and 1)
Two SCBs with two (redundant) RE-1800x2 routing engines (SCB slot 0 and SCB slot
1)
One DPCE-R-4XGE-XFP (slot 3)
High-capacity cooling system
NOTE: The high-capacity cooling system satisfies cooling requirements
of MPCs, and must be used for proper cooling.
