RH2288E V2 altitude requirement

Normal operations of S series switches have requirements for the altitude. An increasing altitude will affect the working temperature range of some switches. You can use Enterprise Network Product Hardware Query Tool to query the operating altitude and temperature of a switch. Click a switch model under Chassis in the query result, and view specifications of this switch.

The differences among the RH1288A V2, RH1288 V2, and RH1288 V3 are listed as follows. The servers' specifications are subject to the official website. ? The RH1288A V2 adopts the Huawei Hi1710 management chip (iBMC), and supports Intel? Xeon? E5-2600 v2 series processors, eight DIMM slots, and two LOM GE electrical ports. ? The RH1288 V2 adopts the management software iMana, and supports Intel? Xeon? E5-2600 and E5-2600 v2 series processors, 24 DIMM slots, and GE or 10GE LOM NIC modules. ? RH1288 V3 adopts the Huawei Hi1710 management chip (iBMC), and supports Intel? Xeon? E5-2600 v3 series processors, 16 DIMM slots, and GE or 10GE LOM NIC modules.

The four NICs of the RH2288 V2 are GE NICs on the mainboard while the NICs of the RH2288H V2 are flexible NICs. The number of PCIe slots on riser cards is also different. The RH2288E V2 supports holding guide rails for installation. For details, see their respective user guide.

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.
