Installing the Host Bus Adapter
The Emulex LPe1250 HBA uses a removable optical transceiver. If you need to change the bracket for
HBA installation, you must first remove this transceiver from its housing (cage). This document explains
how to install the HBA and, if necessary, how to remove the transceiver and bracket safely. To install the
HBA:
1. Each HBA is shipped with several numbers clearly marked on the board. these include
• Institute of Electrical and Electronic Engineers (IEEE) Address
• Worldwide name (WWN)
• Serial number
The IEEE address is a unique 64-bit identifier that you use when configuring your system. The
FC industry uses the WWN derived from the IEEE address for FC connectivity. If the adapter
has two ports, there are two IEEE addresses and two WWNs. Use the serial number when com-
municating with Emulex. Record these numbers before installation.
2. Turn off the computer and unplug it.
3. Remove the computer case.
4. Follow steps 5–12 to change the bracket if they are different sizes. Otherwise, skip to step 13.
5. To change the bracket, you must first remove the transceiver from its cage assembly.
CAUTION: This is a delicate operation–take care not to damage the transceiver.
The HBA uses different types of transceivers. Figure 1 shows an example of one type showing
the bail (handle) extended.

6. To remove the transceiver, pull the bail (handle) out and down to release the latch and gently pull
the transceiver out. Do not force it. After the latch is released, the transceiver slides out easily.
Note: The HBA reports a device ID of 0x1AE5.
Note: The HBA comes with a standard PCIe bracket installed. A low-profile bracket is
included in the box with the HBA. The low-profile mounting bracket is shorter than the
standard bracket; approximately 3.11 in. (7.9 cm) compared to 4.75 in. (12.06 cm)
long.
