Removing a PTX10000 Switch Interface Board
A PTX10008 and a PTX10016 router has six Switch Interface Boards (SIBs) that are located in the middle
of the chassis behind the fan trays. SIB 0 through SIB 2 are located behind the left fan tray and SIB 3
through SIB 5 are located behind the right fan tray. You must remove the appropriate fan tray to access
the failing SIB. See "Removing a PTX10000 Fan Tray" on page
Ensure you have the following equipment on hand before replacing a SIB:
Electrostatic bag or antistatic mat
Electrostatic discharge (ESD) grounding strap

1. Take the SIB offline using the request chassis sib slot slot number offline command.
NOTE: If you suspect the SIB is faulty and want to ensure packets do not flow through the SIB,
power down the SIB instead of taking the SIB offline. To power down the SIB, use the set chassis
sib power-off slot slot number command. To bring up a new SIB up in the slot, you must delete
the old configuration using the delete chassis sib power-off slot slot number command.
2. Place an electrostatic bag or an antistatic mat on a flat, stable surface.
3. Attach the ESD grounding strap to your bare wrist, and connect the strap to the ESD point on the
chassis. There is an ESD point located next to the protective earthing terminal and below PSU 5 on the
