Ensure you have the following equipment on hand before replacing an SFB:
•
Electrostatic bag or antistatic mat
•
Electrostatic discharge (ESD) grounding strap
To remove an SFB (see Figure 104 on page 216 ):
1. Set the fans to full speed by using the test chassis fan tray speed 0 full and test chassis fan tray speed
1 full commands and wait for ten minutes.
2. Take the SFB offline using the request chassis sib slot slot number offline command.
NOTE: If you suspect the SFB is faulty and want to ensure that packets do not flow through
the SFB, power down the SFB instead of taking the SFB offline. To power down the SFB, use
the set chassis sib power-off slot slot number command. To bring up a new SFB in the slot, you
must delete the old configuration using the delete chassis sib power-off slot slot number
command.
3. Place an electrostatic bag or an antistatic mat on a flat, stable surface.
4. Remove the appropriate fan tray (see “Removing an MX10016 Fan Tray” on page 163 ).
5. Wrap and fasten one end of an ESD strap around your bare wrist, and connect the other end of the
strap to the ESD point on the chassis. There is an ESD point located next to the protective earthing
terminal and below PSU 9 on an MX10016 (see Figure 102 on page 214 ).
