Juniper MX10008 User Manual

Removing an MX10008 Switch Fabric Board
An MX10008 router has six Switch Fabric Boards (SFBs) 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 SFB. See “Removing
an MX10008 Fan Tray” on page 179.
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 146 on page 250):
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 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 up 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 MX10008 Fan Tray” on page 179).
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 5 on the MX10008 rear panel (see Figure 144 on page 249).
