Removing and installing the SAS/SATA backplane board To remove the SAS/SATA backplane board: 1 Observe the ESD precautions and pre-installation instructions described on page 35. 2 Remove the air baffles. See “To remove the small air baffle” section on page 45. 3 Make sure all hot-plug HDD carriers are removed from the drive bay. For instructions, see “To remove a HDD” section on page 48. 4 Disconnect all cables attached to the backplane board. 5 Remove the SAS mid-plane board. See previous section. Note: To prevent damage to your system, make sure to remove the mid-plane board first before attempting to remove the backplane board. Hold the backplane board by its edges, then lift it from the chassis. 7 Store the backplane board in an antistatic protective wrapper. 8 Observe the post-installation instructions described on page 36. 3 System upgrade To install the SAS/SATA backplane board: 1 Observe the ESD precautions and pre-installation instructions described on page 35. 2 Remove the air baffles. See “To remove the small air baffle” section on page 45. 3 Make sure all hot-plug HDD carriers are removed from the drive bay. For instructions, see “To remove a HDD” section on page 48. 4 Hold the backplane board only by the edges. Do not push or pull on any components on the backplane. Set the backplane in place at the front of the server system, with the sides of the board resting in the guides at the left and right sides of the server unit. 5 Slide the backplane board into the server system guides at the left and right sides of the server system until the pins at the left and right sides of the backplane bracket are fully inserted into the matching holes in the server system. Observe the post-installation instructions described on page 36. Configuring the integrated SAS hardware RAID components The system supports hardware RAID through the SAS mid-plane and backplane board. The server platform supports RAID 0, 1, 5, 10, and 50 levels. Functionality for hardware RAID is enabled by using the following components: • RAID activation key • RAID cache There is also an option to install the RAID BBU. If power to the storage I/O processor drops below specifications, the RAID BBU maintains the contents of the DIMM by keeping the DIMM in self-refresh mode until power is restored. After power is restored, data can be safely written to drives, maintaining the integrity of the disk array. Removing and installing the RAID activation key To remove the RAID activation key: 1 Observe the ESD precautions and pre-installation instructions described on page 35. 2 Remove the air baffles. See “To remove the small air baffle” section on page 45. 3 Insert the tip of a small flat-bladed screwdriver under the plastic tab on the retainer holding the activation key to the SAS mid- plane board. 4 Gently push down to detach the activation key. 3 System upgrade 5 Store the activation key in an anti-static bag. 6 Observe the post-installation instructions described on page 36. To install the RAID activation key: 1 Observe the ESD precautions and pre-installation instructions described on page 35. 2 Remove the RAID activation key from its protective packaging. 3 Align then insert the activation key into the RAID activation key connector on the SAS mid-plane board. 4 Observe the post-installation instructions described on page 36. Removing and installing the RAID cache To remove the RAID cache: 1 Observe the ESD precautions and pre-installation instructions described on page 35. 2 Remove the air baffles. See “To remove the small air baffle” section on page 45. 3 Press the holding clips on both sides of the slot outward to release the RAID cache (A). Gently pull the RAID cache upward to remove it from the slot (B). 5 Close the clips. 6 Replace the air baffles and CPU air duct. 7 Observe the post-installation instructions described on page 36. To install the RAID cache: 1 Observe the ESD precautions and pre-installation instructions described on page 35. 2 Remove the air baffles. See “To remove the small air baffle” section on page 45. 3 Locate the RAID cache memory (DDR-2) slot on the SAS mid-plane board. 4 Open the clips on the slot. 5 Align then insert the RAID cache into the slot (A). 6 Press the holding clips inward to lock the RAID cache in place (B). Note: Both the RAID activation key and the RAID cache is required to activate the hardware RAID. For instructions on installing the RAID activation key, see page 92. Observe the post-installation instructions described on page 36. 3 System upgrade Removing and installing the RAID BBU To remove the RAID BBU: 1 Observe the ESD precautions and pre-installation instructions described on page 35. 2 Remove the air baffles. See “Removing and installing the air baffles” section on page 42. 3 Disconnect the battery cable from the SAS mid-plane board (A) and detach it from the chassis (B). 4 Remove the battery holder from the chassis. 5 Open the battery holder (A), then detach the cable inside the batte...
