WARNING!
DO NOT SEPARATE THE HEATSINK FROM THE PROCESSOR MODULE.
Damage to the assembly will occur! Only Factory-Repair is authorized to separate assembly.
Return the assembly in the heatsink box using the processor's defective return label.
When the processor/heatsink assembly is removed from the server:
• Do NOT separate the heatsink from the processor.
• Place the intact processor/heatsink assembly, with the handle in the up position, into the extra
ESD bag provided in the heatsink box (if necessary re-use the ESD bag from the processor
box).
• To receive credit for both the processor and the heatsink:
◦ Package the processor/heatsink assembly into the heatsink box.
◦ Place the paper work originally shipped with the processor in the heatsink box.
◦ Apply the processor defective return label to the heatsink box.
Global Customer Services and Support (GCSS) case coding recommendations:
• If the new processor/heatsink assembly is used – (solves the issue or is left in the server for
any reason) – return the defective assembly using the normal process; for example a part
failure code of 74, 75, etc…
• Once assembled, the parts cannot be returned as “Unused”.
In some scenarios assembled parts will not fix an issue, for example:
◦ The new assembly is removed and the original is re-installed in the server.
◦ The wrong speed processor or heatsink combination is assembled.
In these cases:
◦ Use the defective label (B label) from the processor box and apply to the heatsink box.
◦ Use a Parts Failure Code of “AI” on both parts.
NOTE: After replacing the processor and heatsink module use the cpuconfig from UEFI to
verify the that the processor socket has been reconfigured.
SAS backplane
The SAS disk backplane supports two small form factor hard disk drives. The backplane supports
hot-plugging a single SAS drive at a time. The activity LEDs and drive present LEDs are controlled
by a preprogrammed system-on-chip. The system board hosts the SAS controller and supplies 12
V, 5 V, and 3.3 V standby power to the backplane.
The SAS backplane is connected to the system board with a right angle connector. This connector
is specifically designed for high-speed differential applications, and supports server speeds
exceeding 5 Gigabits per second. Power, sense, and I
2
C signals are routed through this connector
as well as the SAS differential pairs and SGPIO signals.
1. Power off the server blade and remove it from the enclosure (“Preparing the server blade for
servicing”).
2. Remove the access panel (“Access panel” (page 113)).
