Chapter 4 Installing and Removing SFCs, RPs, MSCs, PLIMs, and Associated Components
How to Install or Remove a Physical Layer Interface Module
Step 9 Carefully slide the PLIM into the slot until the ejector levers meet the edges of the card cage, then stop when the ejector lever hooks catch the lip of the card cage. If they do not catch, try reinserting the card until the ejector lever hooks are fully latched.
Note PLIMs have guide pins that make initial contact with the midplane connector as you slide a card into its slot.
Step 10 To fully seat the PLIM in the midplane connector, grasp both card ejector levers simultaneously, then push them both inward until they are flush against the front edge of the card carrier. After the guide pins make contact, continue pushing the card carrier until the card ejector levers begin pivoting forward.
Caution Verify that the openings on the card ejector cams pass over the tabs; otherwise, one or both ejector levers may bind when you attempt to close the levers, thereby damaging or breaking one or both of them.
Step 11 To ensure proper EMI shielding and prevent the PLIM from becoming partially dislodged from the midplane, use a screwdriver to fully tighten the captive screws next to each PLIM ejector lever.
Caution To ensure adequate space for additional PLIMs, always tighten the captive installation screws on each newly installed PLIM before you insert another PLIM. These captive screws also prevent accidental removal and provide proper grounding and EMI shielding for the system.
Step 12 If applicable to your system, install the SFP optical modules in a PLIM that uses an SFP module, such as the
What to Do Next
After performing this task:
•Place the impedance carrier in an antistatic bag for storage and future use.
•Verify that the PLIM has been installed properly (see the “Verifying the Installation of a PLIM” section on page
•If you are performing the initial installation of the system and the system includes the grille and doors, install those cosmetic components (see Chapter 5, “Installing and Removing the Doors and Grille”).
Warnings Regarding PLIM Installation
Some PLIMs contain Class 1 lasers, and some contain Class 1M lasers. See the documentation for the specific PLIM for details.
Warning Because invisible laser radiation may be emitted from the aperture of the port when no cable is connected, avoid exposure to laser radiation and do not stare into open apertures. Statement 70
