The following table describes the callouts in Figure 4-2. Item Description 1 Hard drive cage 2 Fan assembly 3 Fan assembly connectors (2) 4 System maintenance switch (SW1) 5 Hard drive cable connector 6 Processor socket 2 7 DIMM bank B 8 Processor socket 1 (populated) 9 DIMM bank A (populated) 10 Adapter card connectors (2) 11 Battery The HP ProLiant BL35p server blades require the support of an HP BladeSystem p-Class sleeve in a server blade enclosure with enhanced backplane components (enhanced server blade enclosure). Each sleeve holds two HP BL35p server blades and installs in a single bay in the enclosure. Up to eight sleeves can be installed in the enclosure and each sleeve holds two blades for a total of 16 HP ProLiant BL35p blades per 6U enclosure. The enhanced server blade enclosure also provides a single rear iLO connector for single-cable remote management of all installed HP ProLiant BL35p server blades. For more information about the enhanced server blade enclosure, see the HP ProLiant BL p-Class Server Blade Enclosure Upgrade Installation Guide or the HP ProLiant BL p-Class Server Blade Enclosure Installation Guide. Each HP ProLiant BL35p server blade includes three network adapters: two Broadcom 5703 Gigabit Ethernet Embedded 10/100/1000T WOL (Wake On LAN) enabled with Preboot eXecution Environment (PXE) plus one additional 10/100T Ethernet adapter dedicated to iLO management. 4.2.1 Supported Memory Configurations Each processor in the HP ProLiant BL35p has a bank consisting of two DIMM slots. The server blade supports up to 8 GB of memory. The following guidelines apply to the HP BL35p DIMMs: • All DIMMs must be PC3200 DDR 400-MHz SDRAM DIMMs. • Both DIMM slots in a bank must be populated. • Both DIMMs in a bank must be identical. • DIMM bank A must always be populated. • DIMM bank B is only active when processor socket 2 is populated. • For best performance, each processor should have a populated memory bank. Caution: Use only HP DIMMs. DIMMs from other sources may adversely affect data integrity. PC3200 DIMMs can either be single- or dual-rank. A dual-rank DIMM is similar to having two separate DIMMs on the same module. Although only a single DIMM module, a dual-rank DIMM acts as if it were two separate DIMMs. The primary reason for the existence of dual-rank DIMMs is to provide the largest capacity DIMM given the current DIMM technology. If the maximum DIMM technology allows for creating 2 GB single-rank DIMMs, a dual-rank DIMM using the same technology would be 4 GB. 156 Server Blades
