Differences between the 4-socket RH5885 V2 and 8-socket RH5885 V2
An 8-socket RH5885 V2 server is made up of two 4-socket RH5885 V2 servers connected through four QPI cables. One of the 4-socket RH5885 V2 servers serves as the master node and the other as the slave node. Hardware differences: ? Rear I/O module: For the 4-socket server, the rear I/O module can be configured with two hard disks and the QPI cables cannot be connected. For the 8-socket server, the rear I/O module cannot be configured with two hard disks and the QPI cables are required. ? Hard disk quantity: 10 (4-socket server); 16 (8-socket server) ? CPU configuration: The 8-socket server must be configured with all CPUs and the 4-socket server can be configured with two or four CPUs. ? DIMM configuration: For the 4-socket server, DIMMs must be symmetrically installed on the memory risers. For the 8-socket server, apart from the symmetry requirements, the DIMMs must be installed on two nodes and the DIMM configuration must be the same on the two memory risers. ? RAID configuration: The 8-socket server requires only one RAID controller card, which must be installed on the master node. Software differences: ? The slave node of the 8-socket server has no BIOS. Therefore, no BIOS information is displayed on iMana. ? The power button on the front panel of the slave node of the 8-socket server is available, but there is no related power control page on the iMana WebUI. ? The iMana of the slave node of the 8-socket server does not provide black box, power-on strategy, system start strategy, and serial port switchover functions.

Whether the RH5885H V3 can be upgraded from 4-socket to 8-socket
The RH5885 V3 and RH5885H V3 cannot be upgraded from a 4-socket to an 8-socket configuration. You can purchase 8-socket RH8100 V3 servers and use them to substitute for RH5885 V3 and RH5885H V3 servers.

Restoring BIOS password
Restore the Server BIOS password as follows: On the iMana or iBMC CLI, run the maintenance -d upgradebios command to restore the BIOS default settings. Use this command with care because all the default BIOS settings are restored after the command is executed. For details, see the iMana User Guide or iBMC User Guide. Before running the maintenance -d upgradebios command, you need to apply for the BIN upgrade package, which may take time. If the BIOS password of a V2 server is lost, use Sandy Bridge (the first digit of the BIOS version is smaller than 3, for example, V060 or V160) and Ivy Bridge (the BIOS version is V3xx) cross-platform BIOS hpm package to restore the password. If the BIOS password of the Sandy Bridge platform is lost, you can upgrade the platform to Ivy Bridge to restore the password. If this method is used, the BMC version must be 5.88 or later (supporting hpm upgrade package). If the BIOS is rolled back so as to obtain the BIOS password. After the BIOS password is obtained, upgrade the BIOS.
