HP L1500 & L3000 (rp5430/rp5470) Internals
Memory
� ECC SDRAM DIMMs
� 256 MB, 512 MB and 1 GB modules supported
� 16 slots
� rp5430: 8.0 GB maximum (the system will not boot if more than 8.0 GB of memory is installed)
� rp5470: 16.0 GB maximum
Expansion
� Two “Twin-Turbo” PCI 64-bit/66 MHz slots, each on an independent PCI bus, each connected
via two I/O channels (aggregate 512 MB/s), hot-plug capable
� rp5430:
� rp5470:
– Four “Turbo” PCI 64-bit/66 MHz slots on three PCI buses, each connected via one I/O channel
(256 MB/s), three of four slots are hot-plug capable
– Six “Turbo” PCI 64-bit/66 MHz slots, each on an independent PCI bus, each connected via
one I/O channel (256 MB/s), hot-plug capable [two of these slots are not active on the
rp5430]
– Two PCI 64-bit/33 MHz slots on a shared bus, on one I/O channel (256 MB/s) [these slots
are not active on the rp5430]
� Two PCI 64-bit/33 MHz slots, reserved for LAN/SCSI and GSP (management) cards, on a shared
bus, on one I/O channel (256 MB/s)
� All PCI slots are 5 V keyed
