electricity through an electrostatic discharge (ESD) event. To prevent ESD damage, maintain
constant contact with any grounded metal surface. A grounding wrist strap is useful for this
purpose. Handle the card carefully at all times and preferably by the edges. Avoid touching
electronic components and keep the card in the original packaging until you are ready for
installation.
The device ID jumpers are used in custom applications. Do not change the jumper settings for a
standard Emulex installation.
The LPe12000 HBA has one six-post jumper block that controls the HBA's device ID. The LPe12002
and LPe12002-X8 HBAs have two six-post jumper blocks that control the HBA's device ID for Ports 0
and 1. The LPe12004 HBA has four six-post jumper blocks that control the HBA's device ID for Ports 0,
1, 2 and 3. Select the ID by installing a jumper between posts 1 and 2, or 3 and 4, or 5 and 6. If no
jumper is installed, the default device ID is 0x1AE5.

attempt to operate the HBA with the PCI device ID set to 0x1AE5 unless
recommended by the driver installation instructions.
