QFX10008 Switch Interface Board
QFX10008 Switch Interface Board Description
Switch Interface Boards (SIBs) create the switch fabric for the QFX10008. Each QFX10008 contains 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. When all six SIBs are installed, the QFX10008 has a net switching capacity of 42 terabits per second (Tbps).
The SIBs make up the QFX10008 switching plane. Five SIBs are required for operation with the sixth providing n+1 redundancy. Each SIB has eight connectors that match and connect to a connector on one of the eight line cards. SIB slots are numbered 0 to 5, numbered from left to right. See Figure 1.
Table 1 shows the physical specifications for a QFX10008 SIB.
Table 1: Dimensions of a QFX10008 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 switch
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.
