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
Install optical modules into the installed PLIMs (for example, install XFP modules in the 14-port 10-GE
XFP PLIM, if this PLIM is installed in your system).
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 4-50
).
•
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.
