Installing a GLM
Use the following steps to install a GLM:

board where the GLM will reside.
1. Insert the new GLM by first placing the cable connection end
of the GLM through the opening on the front of the
controller.
2. Line up the guide pins on the bottom of the replacement
GLM with the holes in the board. Press firmly to seat the
GLM.
3. Press the release lever firmly into place to secure the GLM.
CAUTION: ESD can easily damage a controller or GLM. Wear a
snug-fitting, grounded ESD wrist strap.
Make sure you align the controller in the appropriate guide rails.
If you do not align the controller correctly, damage to the
backplane can occur.
4. Insert the new controller into its slot, and engage its retaining
levers.
5. Connect the host bus cables to the new controller.
NOTE: One or two host bus cables may be attached, depending
on the configuration.

the new controller. Release and replace the ESD cover.
