– For server models with a 4 x 3.5-inch rear drive cage or a GPU installed, a low-profile 7mm drive cage
can be installed only on slot 6.
• Serial port module installation rules:
– For server models with 8 PCIe slots or a 4 x 2.5-inch rear drive cage:
– If both riser 1 and riser 2 use the x16/x16/E riser card and a 7mm drive cage is installed on slot 3,
then a serial port module can be installed on slot 6.
– If only one of riser 1 and riser 2 (not both) uses the x16/x16/E riser card, a 7mm drive cage and a
serial port module cannot be installed at the same time. If no 7mm drive cage is installed, then a
serial port module can be installed on slot 3 or slot 6.
– If both riser 1 and riser 2 do not use the x16/x16/E riser card, no serial port module is supported.
– For server models with an 8 x 2.5-inch/2 x 3.5-inch rear drive cage:
– If riser 1 uses the x16/x16/E riser card, a serial port module can be installed on slot 3 and a 7mm
SSD cage can be installed on slot 6.
– If riser 1 does not use the x16/x16/E riser card, a 7mm drive cage and a serial port module cannot be
installed at the same time. If no 7mm drive cage is installed, then a serial port module can be
installed on slot 6.
– For server models with a 4 x 3.5-inch rear drive cage, a 7mm drive cage and a serial port module
cannot be installed at the same time. If no 7mm drive cage is installed, then a serial port module can be
installed on slot 3 or slot 6.
– For server models with a double-wide GPU, the serial port module can be installed only on slot 6.
