For memory upgrade in the Cisco ASA 5510 with four memory sockets, use slot 1 - P13 and note that only one slot must be populated at all times. For optimum performance in the Cisco ASA 5520 and the Cisco ASA 5540 , install the DIMMs in slots P13 and P15, if you are populating only two slots.
Cisco ASA 5500 Series Adaptive Security Appliance Hardware Installation Guide mistakenly instructs to use slots 1 and 3 or slots 2 and 4 for memory upgrades on some ASA 5510 boxes with 4 memory sockets. On the contrary, the Dual In-line Memory Module (DIMM) should only be inserted in slot 1 on all ASA 5510 devices; slots 2-4 should not be used. This defect is filed to correct the documentation.
This bug is not accurate. The doc is correct.
The original ASA-5510s shipped with 4 DIMM sockets. Only after production for
about a year was the 5510 re-worked and we came out with a cost reduced model
which reduced the DIMM sockets from 4 to 1. This was verified by MFG.
