NOTE: In MX10004-3F-BASE and MX10004-4F-PREM configurations with MX10K-LC9600 line
cards installed the fabric capacity is only 52% and 69% respectively. When you try to use all the
ports on the line cards, it leads to fabric over-subscription. To prevent fabric over-subscriptions,
you must use only the odd-numbered ports or only the even-numbered ports.
NOTE: You must order line cards and the cable management system separately. They are not part
of the base or redundant configuration.
NOTE: If you want to purchase additional power supplies (AC, DC, HVAC, or HVDC), SFBs, or
RCBs for your router configuration, you must order them separately.
MX10004 Component Redundancy
The MX10004 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 MX10004 router can have one or two RCBs. When two
RCBs are installed, one functions as the primary RCB, and the other functions as the backup RCB. If
the primary RCB (or either of its components) fails, the backup RCB can take over as primary. See
"MX10004 Routing and Control Board Components and Descriptions" on page 56
.
• Switch Fabric Boards (SFBs)—The MX10004 has six SFB slots for the JNP10004-SF2 SFBs. The
switch fabric requires a minimum of three SFBs to provide the reduced switching functionality to an
MX10004 router. You can achieve 5+1 SFB redundancy, only when the MX10004 router is
populated with MX10K-LC2101 or MX10K-LC480 line cards or a mix of the two line cards. You must
install all six SFBs for MX10K-LC9600 line card support.
• Power supplies—The system requires two power supplies for minimum operation. If you install three
power supplies, the third power supply provides 2+1 redundancy. If one power supply fails in a fully
redundant system, the other power supplies can provide full power to the MX10004 router
indefinitely.
With the power supply redundancy, when one power supply fails, it does not cause line cards to go
offline. Only the
No Redundant Power
minor alarm is raised. You can disable this alarm by using the
set
chassis no-psu-redundancy
command.
