Installing or removing the optical module
The optical module enables you to connect two network devices with optical fiber cables. The optical
module is needed only on some PCIe cards.
Note: The optical module is extremely sensitive to ESD. Ensure that you read and understand “Handling
static-sensitive devices” on page 54 first and carefully perform the operation.
Installing the optical module
Attention: Do not open your server or attempt any repair before reading and understanding “Safety information”
on page iii and “Guidelines” on page 53.
Before you begin, print all the related instructions or ensure that you can view the PDF version on another
computer for reference.
Notes:
• The optical module and the PCIe card might look different from the illustration in this topic.
• Before you install the optical module, ensure that the PCIe card that requires the optical module is
installed in the server. See “Installing a PCIe card” on page 81.
To install the optical module, do the following:
1. Locate the two holes at the rear of the PCIe card for installing the optical module.
2. Touch the static-protective package that contains the optical module to any unpainted surface on the
outside of the server. Then, take the optical module out of the package.
3. With the optical module handle in the open position, insert the optical module into one of the two
holes in the PCIe card.
