Table 87: MX960 Zoning

Chassis Power Configuration
MX960 DC (normal-capacity and high-capacity
power supplies); MX960 AC (high-capacity power
supplies)
MX960 DC (normal-capacity and high-capacity
power supplies); MX960 AC (high-capacity power
supplies)
180
Both normal-capacity and high-capacity MX960 chassis with DC power supplies and
MX960 chassis with high-capacity AC power supplies are zoned. MX960 chassis with
normal-capacity AC power supplies have one overall zone. Zoning means that certain
components are powered by specific power supplies (see
information on zoning). When calculating power requirements, be sure that there is
adequate power for each zone.
Three AC power supplies are mandatory for MX960 chassis with normal-capacity AC
power supplies.
Zone
Zone 0
Zone 1
The following sample configuration shows an MX960 chassis with:
Four high-capacity AC power supplies (using two feeds for each power supply); two
supplies are active, two are redundant
Six 16 port 10 GbE MPC with SFP+ interfaces (slots 0 through 5)
Two SCBs with two (redundant) RE-1800x2 routing engines (SCB slot 0 and SCB slot
1)
SCB (SCB slot 6)
Five 16 port 10 GbE MPC with SFP+ interfaces (slots 7 through 11)
High-capacity cooling system (upper and lower fan trays)
NOTE: The high-capacity cooling system satisfies cooling requirements
of MPCs, and must be used for proper cooling.
