Install an MX10004 Switch Fabric Board
A Juniper Networks MX10004 router has up to six SFBs that are located in the middle of the chassis
behind the fan trays. SIB 0 through SIB 2 are located behind the le fan tray, and SIB 3 through SIB 5
are located behind the right fan tray. You must remove the appropriate fan tray to install an SFB. See
"Remove an MX10004 Fan Tray" on page 166.
NOTE: When replacing the fans or SFBs at 40° C chassis ambient temperature, ensure that the
fans run at 100% fan speed for at least 10 minutes before replacing the fans or SFBs.
Use the test chassis fan tray 0 speed full-speed and test chassis fan tray 1 speed full-speed
commands to set the chassis fans to 100% speed.
Aer replacing the fans or SFBs, set the fans to normal speed using the test chassis fan tray 0
speed normal and test chassis fan tray 1 speed normal command.
If you plan to replace one or more Switch Fabric Boards (SFBs), make sure you calculate the me
required to remove the fan tray, add or replace the SFBs, and install the fan tray in the chassis. To
calculate the me allowed for replacing a SFB, see Table 52 on page 175.
