PCI Expansion Slots
Sun Fire X4100 M2 Server PCI Expansion Slots
The Sun Fire X4100 M2 server features 2 PCI-E expansion slots. When viewing the server from the rear, PCI 0 is the lefthand slot and
PCI 1 is the righthand slot. Both slots are Low Profile 8-lane PCI-Express expansion slots supporting up to 8-lane PCI-E expansion
cards.
Sun Fire X4200 M2 Server PCI Expansion Slots
The Sun Fire X4200 M2 server offers 4 PCI-Express and 1 PCI-X expansion slots. When viewing the server from the rear, the PCI slots
are present in numeric order from left to right and numbered from 0 to 4.
PCI0 and PCI1 are Low Profile 8-lane PCI-Express expansion slots supporting up to 8-lane PCI-E expansion cards. PCI2 is a 133MHz/64-
bit MD2 PCI-X slot supporting both 33 and 66 MHz PCI expansion cards and 66, 100, and 133 MHz PCI-X expansion cards. PCI 3 and PCI
4 are both Low Profile 8-lane PCI-Express expansion slots supporting up to 8-lane PCI-E expansion cards.
The PCI-X slot on the Sun Fire X4200 M2 server use a 3.3 Volt signaling bus. Therefore, it only supports 3.3 Volt keyed MD2 expansion
cards. The use of 5 Volt keyed expansion cards is unsupported and will result in damage to the motherboard. There are 2 defined
card lengths for low profile PCI-X expansion cards, MD1 and MD2. MD1 defines the shortest 32-bit card length available, 4.721 inches
(119.91 mm). MD2 defines the maximum length of low profile PCI card available, 6.600 inches (167.64 mm). Any low profile PCI card
that is longer that the MD1 definition but shorter that the MD2 definition is considered to be MD2 form factor. The two card lengths
enable system designers to support either all low profile PCI cards, which includes MD1 and MD2, or limit their design to support
only MD1 cards.
