Figure 23 Grounding the router with a grounding strip
Grounding the router with a grounding conductor buried in
the earth ground
If the installation site has no grounding strips, but earth ground is available, hammer a 0.5 m (1.64 ft)
or longer angle iron or steel tube into the earth ground to serve as a grounding conductor. The steel
tube must be zinc-coated. Weld the yellow-green grounding cable to the angel iron or steel tube and
treat the joint for corrosion protection.
Installing an interface module
Installing a SIC
CAUTION:
SIC interface modules are not hot swappable. Make sure the router is powered off before installing a
SIC.
To install a SIC:
1. Remove the fastening screws with a Phillips screwdriver to remove the filler panel.
Keep the removed filler panel for future use.
2. Push the SIC slowly along the slide rails into the slot until it makes close contact with the
backplane of the router.
3. Use a Phillips screwdriver to fasten the captive screws on the SIC.
