Installing the Host Bus Adapter
The Emulex LPe12000, LPe12002 and LPe12004 host bus adapters (HBAs) use removable optical
transceivers. If you need to change the bracket for HBA installation, you must first remove the optical
transceiver(s), if installed, from the 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
• IEEE Address
• World Wide 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 Institute of Electrical and Electronics Engineers
(IEEE) address for FC connectivity. If the adapter has two ports, there are two IEEE addresses
and two WWNs. If the adapter has four ports, there are four IEEE addresses and four WWNs.
Use the serial number when communicating with Emulex. Record these numbers before installa-
tion.
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.
The HBA uses different types of transceivers. Figure 2 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 comes with a standard PCIe bracket installed. A low-profile bracket is
included in the box with the LPe12000, LPe12002 HBAs. (The LPe12004 will not fit in
a half height slot.) 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.
Caution: This is a delicate operation–take care not to damage the transceiver.
