Before you begin
This procedure requires that the EEPROM on the midplane board be
programmed with the product salable serial number. You will need a
PC or laptop with a serial port, a terminal emulation program, and the
serial cable (part number 259992–001) provided with the midplane
spare kit.
Observe the following precautions when replacing the midplane.
CAUTION:
Parts can be damaged by electrostatic discharge. Use proper
anti-static protection. Refer to the documentation that shipped
with your system for additional information.
Slate blue-colored items, such as the midplane thumbscrews,
means their attached component is not hot-swappable. Power
to the disk enclosure must be shut down before the component
is removed.
Verifying component failure
Before replacing the midplane, verify its failure by checking the LED
status of the following components:
• Disk drives—Test with a known good disk drive (see Table 1).
• I/O module—Test with a known good I/O module (see Table 2).
• Fan module—Test with a known good fan module (see Table 2).
