PTX10016 Switch Fabric

The PTX10016 comes with two models of SIBs:

• The JNP10016-SF SIB has a switching capacity of 14.4 Tbps in one direction and supports Junos OS.
• The JNP10016-SF3 SIB has a switching capacity of 45.9 Tbps in one direction and supports:
  • Junos OS Evolved Release 21.2R2 and later 21.2 releases
  • Junos OS Evolved Release 21.4R1 and later

The SIBs make up the PTX10016 routing plane. In configurations that support JNP10016-SF SIBs, five SIBs are required for base operation, and the sixth provides 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. See Figure 1.

Table 1 lists the physical specifications of a JNP10016-SF SIB. Table 2 lists the physical specifications of a JNP10016-SF3 SIB.

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 SIB0 to SIB5, with SIB0 located next to the power supplies. See Figure 3.

The SIB has two status LEDs at the top of each board. See Figure 4.

Table 3 describes the functions of these LEDs.

Table 3: Functions of the SIB LEDs

Label	Color	State	Description
PWR (Power)	Green	On steadily	The SIB is receiving power.
	Yellow	Blinking	Power fault.
	Unlit	Off	The SIB is either offline or not receiving power.
STAT (Status)	Green	On steadily	The SIB is online and functioning normally.
	Green	Blinking	The beacon feature is enabled.
	Yellow	On steadily	The SIB has failed.
	Unlit	Off	The SIB is offline.
