2)
Face the router rear panel, and remove the blank panel with screwdrivers.
3)
Flush the line card interface board and the edge of the opening of the back panel of the router base.
4)
Push the line card to the router until the interface board closely touches the backplane of the router.
5)
Tighten the fastening screws on the line card.
6)
Repeat Step 3 through Step 5 until all the line cards have been installed.
Before installing line cards, switch off all power supply connected to the router. Otherwise, electric shock or
device damage may occur.
At Step 3 and Step 4, operate gently. A line card should be inserted gently and smoothly. If you find it difficult
to push the line card, do not adopt forcible measures. Instead, unplug the line card and check if the SIC card
interface board has been aligned with the edge of the opening on the rear panel at the base of the router.
Otherwise, the line card may be damaged.
Removing Line Cards
1)
Switch off the router.
2)
Face the router rear panel.
3)
Unplug the cables of the ports on the module to be removed.
4)
Remove the fastening screws on the two sides of the line card interface board with a straight screwdriver.
5)
Draw the line card to the front of you until the interface board completely disengages from the base of the router.
6)
Repeat Step 4 and Step 5 until all required line card interface boards have been removed.
When you have removed a line card and are not going to install another one, install an SIC slot baffle in time
to protect it against dust and ensure ventilation.
When you remove a line card, keep it distant from the passage in the working room to avoid any damage or
accident due to bumping during removal.
Troubleshooting Line Cards
Troubleshooting line cards as follows if the router fails to operate after you have installed a line card:
Check the interface cable of the module to see if the correct cable has been used.
Observe the interface indicators of various modules to see if the module is working properly.
In privileged EXEC mode, view interface information. Check whether each line card has accepted configuration and
is operational.
Verification
Perform the following verification steps before powering up an installed router:
If the router is stalled in a cabinet, verify the installation brackets of the cabinet and router are fixed. If the router is
stalled on the workbench, verify whether there is enough room around the router for heat dissipation and whether the
workbench is fixed.
