1.1.1 Network Port Assignments
The HP Integrity rx1620 has three network ports:
• LAN A, a 10/100/1000 base-T Ethernet LAN A Gb port, optionally connected to the local
WAN, enabling remote access.
• LAN B, a 10/100/1000 base-T Ethernet LAN A Gb port, connected to the administrative
network.
• LAN C, a 10/100 Ethernet port for the Management Processor (MP) card. This port is
connected to the cluster's console network switch.
Refer to the cluster's cabling tables for more information.
1.1.2 Supported Memory Configurations
The HP Cluster Platform does not enforce any memory configuration rules on the HP Integrity
rx1620 nodes other than those associated with the server. For the HP Integrity rx1620 these rules
are:
1. The system has eight memory slots for installing DDR SDRAM memory modules.
2. The system supports a maximum of 16 GB of memory and a minimum of 512 MB.
3. Memory modules can either be 256MB, 512MB, 1GB, or 2GB, and they must be arranged as
ordered pairs of equal size. For example, if you place a 1 GB memory module in slot 0A then
you must insert a 1 GB memory module in slot 0B.
4. Memory in the rx1620 must be loaded in quads. This means that you must load two memory
cards per cell. For example, using the loading order in rule 3, place DIMMs in slots 0A and
0B of memory cell 0 and in slots 1A and 1B of memory cell 1.
5. DDR SDRAM must be loaded as matched pairs. To determine if the DIMMs are matched
pairs, look at the HP part number on the DIMMs. If the HP part numbers match, then the
DIMMs can be loaded together as pairs.
6. You can mix module sizes in the system, provided that the DIMMs within each pair share
the same HP part number. For example, you can load a pair of 256 MB DIMMs in slots 0A
and 0B, a pair of 1 GB DIMMs in slots 1A and 1B, and pairs of 512 MB DIMMs in slots 2A,
2B, 3A, and 3B.
7. You must install the first DDR SDRAM matched pair in memory cell 0 and in the slots labeled
0A and 0B. Load the second matched pair in memory cell 1 and in the slots labeled 1A and
1B. Continue loading successive matched pairs.
The HP Integrity rx1620 supports the chip spare feature, enabling the server's error handling to
bypass an entire DDR SDRAM chip on a DIMM if a multibit error is detected. To use the chip
spare feature, you must install only DIMMs built with x4 SDRAM. Load the memory in quads,
