This is a write-up of the hardware found in Juniper SA4000 and SA4500 since I could not find that on the Intarweb. We don't use them anymore so I opened them, breaking seals, voiding warranty. Now we use OpenVPN for remote access.
| SA4000 | SA4500 | |
| Motherboard | Supermicro X6DVL-EG2JN | Supermicro PDSMP-JN001 plus Supermicro AOC-IO-U2G |
| Processor | Intel Xeon 3.2 GHz (maybe this one) | Intel E4300 1.8 GHz |
| Memory | 2 x 512 MB PC2-3200R (ECC) | 2 x 512 MB PC5300 (ECC) |
| BIOS | AMIBIOS, Juniper Networks - BIOS 4000 | Phoenix, Juniper Networks MR Production BIOS |
| Crypto hardware | Yes, on PCI card | No |
| Harddisk | 80 GB WDC WD800BB PATA | 160 GB WD Caviar Blue SATA |
| External connections | Serial, 2 x GbE | Serial, 2 x GbE, USB, Compact Flash |
| Internal connections | PATA, 2 x SATA, USB | Serial, 4 x SATA, VGA, USB |
| PSU | 260 W | 300 W |
| Console needs Cisco / Sun dongle | Yes | No |
The X6DVL-EG2JN motherboard is like the X6DVL-EG2, but without VGA, USB and PS/2 connectors.
The PDSMP-JN001 motherboard is like the PDSMP-i, but has a different form factor and with unusually oriented PCIe connectors for the interface bays.
The SA4500 has the serial port and GbE ports on an Supermicro AOC-IO-U2G add on card.
The SA4500 Compact Flash slot is behind the dimple on the back. The bracket blocking it can be removed after removal of the harddisk, which is mounted with 4 screws on the bottom.
The SA4500 boots LILO and then probably Linux.
Adding memory that physically fits does not work - only beep-beep. The box came with 2 x PC2-5300E-555-13-F0. The slots are labled "UNB ECC DDR2 REQUIRED".
Attaching a VGA display to the connector in the middle of the motherboard and USB keyboard to the external port work. Pressing [Del] gives access to BIOS settings.
Here are the kernel boot messages.
