MX10004 Switch Fabric Board

The MX10004 Switch Fabric Boards (SFBs) form the switch fabric for the router.

MX10004 Switch Fabric Board Description

Switch Fabric Boards (SFBs) create the switch fabric for the MX10004. Each MX10004 contains between three and six SFBs that are installed vertically, mid-chassis, between the line cards and the RCBs in the front and the fan trays in the rear.

The ZF ASIC based JNP10004-SF2 SFBs make up the MX10004 switching plane that provide fabric inter-connect for the custom silicon line-cards with 2.4 Tbps, 480 Gbps and 9.6 Tbps throughput. Each SFB has four connectors that correspond to a matching connector on one of the four line cards (see Figure 1).

MX10004 supports six SFBs. Depending on the type of line card used, there can be fabric card redundancy (5+1) or no redundancy.

Note:

Hyper-mode is the default forwarding mode on the JNP10004-SF2 SFB.

Table 1 shows the specifications of JNP10004-SF2 SFBs.

Table 1: JNP10004-SF2 SFB Specifications
Specification	JNP10004-SF2
Operating system	Junos OS Release 22.3R1 and later
Supported line cards	MX10K-LC2101 MX10K-LC480 MX10K-LC9600
Number of SFBs required for maximum throughput	Based on the line card installed: MX10K-LC2101 - 5+1 (fabric redundancy) MX10K-LC480 - 5+1 (fabric redundancy) MX10K-LC9600 - 6+0 (no fabric redundancy)
Switching Capacity	When all six SFBs are installed, based on the line card installed, the MX10004 has a net switching capacity of 38.4 Tbps.
Height	9.43 in. (23.95 cm)
Width	1.77 in. (4.48 cm)
Depth	13.4 in. (34.6 cm)
Weight	8 lb (3.6 kg)

SFBs are hot-removable and hot-insertable field-replaceable units (FRUs). They are not visible from the outside of the router chassis. You must remove one of the fan trays in order to view the SFBs. The SFBs are numbered from left to right SFB0 to SFB5. See Figure 2.
