MX10016 Component Redundancy
The MX10016 router is designed so that no single point of failure can cause the entire system to fail. The
following major hardware components in the redundant configuration provide redundancy:
•
Routing and Control Board (RCB)—The RCB consolidates the Routing Engine function with the control
plane function in a single unit. The MX10016 router can have one RCB in a base configuration or two
RCBs in a redundant configuration. When two RCBs are installed, one functions as the master and the
other functions as the backup. If the master RCB (or either of its components) fails, the backup can take
over as the master. See
“MX10016 Routing and Control Board” on page 75
•
Switch Fabric Boards (SFBs)—The MX10016 router has six SFB slots. Five SFBs are required for base
operation and the sixth SFB provides n+1 redundancy. All six SFBs are active and can sustain full
throughput rate. The fabric plane can tolerate one SFB failure without any loss of performance. See
“MX10016 Switch Fabric Board” on page 80
.
•
Power supplies—The MX10016 router requires three power supplies for minimum operation. Additional
power supplies, provide n+1 redundancy for the system. AC, DC, HVAC, and HVDC systems tolerate a
single power supply to fail without system interruption. If one power supply fails in a fully redundant
system, the other power supplies can provide full power to the MX10016 router indefinitely.
The MX10016 router also supports source redundancy. Two sets of lugs are provided for the
JNP10K-PWR-AC cables, four sets of lugs are provided for the JNP10K-PWR-DC2 cables, and two AC
power cords are provided for each JNP10K-PWR-AC2 power supply.
•
Cooling system—The fan trays have redundant fans, which are controlled by the fan tray controller. If
one of the fans fails, the host subsystem increases the speed of the remaining fans to provide sufficient
cooling for the router indefinitely. See
“MX10016 Cooling System” on page 44
