QFX10016 Switch Interface Board
QFX10016 Switch Interface Board Description
Switch Interface Boards (SIBs) create the switch fabric for the QFX10016. Each QFX10016 contains six SIBs that are installed vertically, mid-chassis, between the line cards and the Routing and Control Boards (RCBs) in the front and the fan trays in the rear. When all six SIBs are installed, the QFX10016 has a net switching capacity of 96 terabits per second (Tbps).
The SIBs make up the QFX10016 switching plane. Five SIBs are required for operation, with the sixth providing n+1 redundancy. The sixth SIB is powered and available to the system at all times. Each SIB has 16 connectors that match and connect to a connector on one of the 16 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 QFX10016 SIB.
Table 1: Dimensions of a QFX10016 SIB
34.6 in. (87.88 cm)
1.8 in. (4.57 cm)
10.4 in. (26.42 cm)
35.2 lb (15.97 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
next to the power supplies. See Figure 2.
