PTX10008 Switch Fabric
The PTX10000 Switch Interface Boards (SIBs) form the switch fabric for the router.
PTX10008 Switch Interface Board Description
Switch Interface Boards (SIBs) create the switch fabric for the PTX10008. Each PTX10008 contains five or six SIBs that are installed vertically, mid-chassis, between the line cards and the RCBs in the front and the fan trays in the rear.
The SIBs make up the PTX10008 switching plane. Five SIBs are required for operation with the sixth providing n+1 redundancy. When all six SIBs are installed, the PTX10008 has a net switching capacity of 42 terabits. Each SIB has eight connectors that match and connect to a connector on one of the eight line cards. See Figure 1.
Table 1 shows the physical specifications for a PTX10008 SIB.
Table 1: Dimensions of a PTX10008 SIB
19.7 in. (50.04 cm)
1.8 in. (4.57 cm)
10.4 in. (26.42 cm)
14.8 lb (6.71 kg)
SIBs 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
SIBs. The SIBs are numbered from left to right
SIB5. See Figure 2.

PTX10000 Switch Interface Board LEDs
The Switch Interface Board (SIB) has two status LEDs at the top of each board. See Figure 3.
Table 2 describes the functions of these LEDs.
