Installing and Removing a Blank Line Card
When a line card slot is not in use, a blank line card must fill the empty slot to allow the switch to conform
to electromagnetic interference (EMI) emissions requirements and to allow proper airflow across the line
cards.

Step 1
This procedure shows how to insert a blank line card in a line card slot:
a) Hold the front of the blank line card with one hand and place your other hand under the blank line card.
b) Align the back of the blank line card to the guides in the open line card slot and slide the blank line card all the way
into the slot. The two latches on the sides of the blank line card should be locked onto the brackets on the side of the
chassis.
Note
To prevent jamming the blank line card between the upper and the lower edges of the slot make certain
that the blank line card is positioned correctly, as shown in the following illustration.
Note
The latches are stiff and may require extra force to fully engage with the brackets on the sides of the chassis.
Statement 1034 Backplane Voltage
Hazardous voltage or energy is present on the backplane when the system is operating. Use caution
when servicing.
Statement 1029 Blank Faceplates and Cover Panels
Blank faceplates and cover panels serve three important functions: they prevent exposure to hazardous
voltages and currents inside the chassis; they contain electromagnetic interference (EMI) that might
disrupt other equipment; and they direct the flow of cooling air through the chassis. Do not operate the
system unless all cards, faceplates, front covers, and rear covers are in place.
Statement 1051 Laser Radiation
Invisible laser radiation may be emitted from disconnected fibers or connectors. Do not stare into beams
or view directly with optical instruments.
