HP ProLiant DL380 G7 with BrookTrout Fax Boards

While many of the newer Dialogic BrookTrout fax boards are shrinking in size, there are quite a few Full Size fax boards out there. These are a major factor that you should keep in mind when choosing your physical server to house your fax boards.

Recently I had to install 2 Full Size – Dialogic BrookTrout TR1034+E8-8L-R analog fax boards into an HP ProLiant DL380 G7. On initial inspection you would think that these will not fit. However as with all DL380’s, HP have packed so much into this server.

Looking closely at the expansion card cage, you will see that Slot 1 and Slot 4 will allow for two full length cards. The cards that we installed were PCI Express cards, but looking at the HP ProLiant DL380 G7 Quick Specs there are two PCIe/PCI-X Riser cards that you can purchase (one Primary, the other Secondary). These will allow you to re-use any of your older PCI-X fax boards.

As you can see from the picture above and below, both cards fit in the server fine.

Word of Warning \ Disclaimer There are a few versions of PCI BrookTrout Fax Boards. While the PCI-X cards should fit in the server, the older PCI cards will not. Make sure that you check with your hardware provider that the server will accept your fax board.
PCI-X is often confused by name with PCI Express, commonly abbreviated as PCI-E or PCIe, although the cards themselves are totally incompatible and look different. The reason for this confusion is that “PCI-X” sounds similar to “PCI Express”. While they are both high-speed computer buses for internal peripherals, they differ in many ways. The first is that PCI-X is a 64-bit parallel interface that is backward compatible with 32-bit PCI devices. PCIe is a serial bus with a different physical interface that was designed to supersede both PCI and PCI-X.

    Hi Kieran,

    I’m a noob on server tech, especially with system boards. I have some questions regarding DL380 g7 server and I hope you can help me with it.
    1. So basically your BrookTrout cards are PCIe type and can be attached to DL380 g7 server without any additional riser. Am I correct?
    2. If I have a PCI card (full lengh, full size just like your cards) what kind of riser card I should buy? Can I use this one?

    Thank you,

      Hi Setyo,
      Looking at the specs for that card, it says it ” This PCIe to PCI Card lets you use low profile PCI expansion cards in a server or desktop motherboard PCI Express slot”.
      If you are using a full height card you may run into problems. In order for use a full height / full length PCI-X card card you will need to use an HP riser board that fits into the expansion cage.
      Hope that helps.

    Hi Kieran,

    I have a problem with using a Dialogic ISDN card on a PCI-X riser on DL 380 G7. The card is working without problems in ML 350 G6 in a PCI-X riser but does not even get the powered on when it is fitted in the DL server. Even though your article is not exactly about my problem, you seem to have some experience with HP servers, risers and Dialogic cards so it is worth a shot to get some feedback from you. 😉

    Kind regards,

      Hi Goran

      I have never had such an issue, especially with an HP server. I wonder is the riser seated correctly into the slot on the motherboard. Are there any other cards connected to the riser?
