The sFU-8 is factory-installed in a chassis when it is shipped. Providing the chassis has a
functioning sFU-4 fan module, you can hot-swap the sFU-8 without interruption to the operation
of the interconnect and without disconnecting it from power.
Warning!
Never remove both the sFU-4 and sFU-8 modules at the same time. One fan module must be
installed and running at all times when the interconnect is operating.
In the unlikely event that the replacement sFU-8 is defective, be prepared to shut the interconnect
down quickly to prevent an over-temperature condition.
Use the following procedure to replace a defective fan module by hot-swap:
1. Unpack and prepare all components on a convenient work surface adjacent to the chassis
before you begin the swap procedure. This will enable you to preform the swap quickly.
2. Before starting the procedure, ensure that the sFU-4 module is functioning correctly.
3. Loosen the screws that secure the sFU-8 to the chassis.
4. Remove the sFU-48 by sliding it out of the chassis.
5. Align the replacement sFU-8 so that it is level and square with the slot.
6. Slide in the sFU-4 until it engages with the connector on the chassis mid-plane. The fans will
begin to spin up immediately.
7. Replace and secure the screws.
8. Listen for proper sFU-8 fan operation and check the LEDs for correct operation as shown
in Table

Description
This LED indicates an over-temperature fault on the chassis. When present, this usually indicates
a problem with one of the fan modules.
• Illuminated: An over-temperature fault is detected
• Off: Temperature levels are normal.
This LED indicates that at least one of the four fans has failed in the other fan module (the sFU-4).
This LED indicates that at least one of the eight sFU-8 fans has failed. Providing the vertical
sFU-4 module is functioning correctly, you can hot-swap this failed sFU-8 module.
This LED indicates that at least one of the optional five main AC-DC power supplies have an
AC or DC fault. Verify the fault by checking the PSU LEDs
6-8.
