MX2000-SFB-S Switch Fabric Board Description
MX2000-SFB-S switch fabric boards (SFB) create a highly scalable and resilient “all-active” centralized switch fabric that delivers up to 860 Gbps per slot of full-duplex switching capacity to each Modular Port Concentrator (MPC) in an MX2000 series router. Each SFB hosts one switch fabric plane made of two fabric chipsets. You can install up to eight SFB2s in an MX2000 series router. Only seven SFB2s are required for line rate operation
Note that you can’t mix switch fabric board models (SFB, SFB2, SFB3) in a single MX2000 series router chassis. If you upgrade from one model to another, the MX2000 series router will support both models at the same time but only for the duration of the upgrade.
Figure 1 shows the MX2000 Switch Fabric Board (SFB).

Features and Components
The MX2000-SFB-S provides:
Switch Fabric Board Slots
You can install up to eight SFBs in an MX2000 router. The SFBs install vertically into the front of the router chassis in the slots labeled 0 through 7.
Slot 0 must always have a functioning SFB. If the SFB in slot 0 fails, replace it with a functioning SFB from another slot, and then install a blank panel in the other slot. If slots 1 through 7 are empty, install a blank panel in them. You cannot install a blank panel in slot 0.
Caution: If an SFB fails, don’t remove it until you have a replacement SFB or blank panel ready to install.
Switch Fabric Board Redundancy
For line rate operation, the MX2000 series router must have at least seven SFBs installed. Although MX2000 routers can operate with fewer than seven SFBs, packet forwarding performance is impacted.
Weight and Dimensions
Maximum Power Requirements (without MICs)
During an upgrade from SFB to SFB2, MX2000 series routers support both SFB and SFB2 at the same time for the duration of the upgrade.
