PTX10008 Switch Fabric

The PTX10008 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. The SIBs are installed vertically, mid-chassis, between the line cards and the RCBs in the front and the fan trays in the rear.

The following SIB models make up the PTX10008 switching plane: the JNP10008-SF (see Figure 1), the JNP10008-SF3 (see Figure 2), and the JNP10008-SF5 (Figure 3). You must use the same SIB model type in a running chassis. Each SIB model has eight connectors, each of which matches and connects to a connector on one of the eight line cards. The JNP10008-SF SIB supports five standard line cards and Junos OS. The JNP10008-SF3 SIB supports the 14.4 Tbps line cards and Junos OS Evolved. The JNP10008-SF5 SIB supports the PTX10K-LC1201-36CD, PTX10K-LC1202-36MR, and PTX10K-LC1301-36DD line cards and Junos OS Evolved. See Table 1 for a comparison of the models.

Number of SIBs required for operation

Base systems require five SIBs; redundant systems require six SIBs

Base systems require three SIBs; partial-bandwidth PREM2 systems require four SIBs; and full-bandwidth redundant systems require six SIBs. All six SIBs must be installed and active to deliver the full throughput rate of the chassis. With JNP10008-SF3, there is no redundancy for switch fabric. Each of the six SIBs provides one-sixth of the full switching fabric bandwidth.

SIBs are hot-removable and hot-insertable field-replaceable units (FRUs). They are not visible from the outside of the router chassis. If you don’t know which SIB you have installed, you can use the CLI command show chassis hardware models. Otherwise, you must remove one of the fan trays in order to view the SIBs. For instructions on removing the fan trays, see Remove a PTX10008 Fan Tray. The SIBs are numbered SIB0 through SIB5 from left to right. See Figure 4.

The boot time for the JNP10008-SF5 SIB is approximately 232 seconds.

PTX10008 Switch Interface Board LEDs

The Switch Interface Board (SIB) has two LEDs.
