About these instructions
This document contains instructions for installing a gigabit link module (GLM) in an HP StorageWorks HSG60 or HSG80 array controller. Note: For instructions on upgrading a single-controller configuration to a dual-redundant controller configuration, refer to the appropriate array controller user guide or maintenance and service guide. Procedures in these instructions: ■ Replacing a GLM in single-controller configurations, page 1 ■ Replacing a GLM in dual-redundant controller
configurations, page 2
General information Figure 1 shows the location of GLMs in an HSG60 or HSG80 controller. Figure 1: Location of GLMs in an HSG60 or HSG80 controller Tip: Refer to Figure 1 while completing removal and installation procedures and for reference of specific controller components.
Replacing a GLM in single-controller configurations Use the steps in “Removing a GLM” and “Installing a GLM” to replace a GLM in single-controller configurations.
Caution: Static electricity can easily damage a controller or GLM. Wear a snug-fitting, grounded electrostatic discharge (ESD) wrist strap.
Removing a GLM Use the following steps to remove a GLM in single-controller configurations: 1. Check the controller to make sure it is operating:
■ If the controller is operating, connect a PC or terminal to
the controller maintenance port of the failed GLM.
■ If the controller is not operating, go to step 6.
2. From the host console, stop all host activity to the controller,
and then dismount the logical units in the subsystem.
3. For Microsoft
® Windows 2000® or Windows NT® platform
users, shut down the server.
4. Run the Fault Management Utility (FMU) to obtain the last
failure codes, if desired.
5. Shut down “this controller” by entering the following
command:
SHUTDOWN THIS_CONTROLLER
Note: After the controller shuts down, the Reset button and the first three port LEDs turn on (see Figure 2). This can take several minutes depending on the amount of data that needs to be flushed from the cache module. Figure 2: Controller Reset button and first three port LEDs on the OCP 6. Disconnect all host bus cables from the controller.
Caution: For fiber optic cables without extender clips, use thin needle nose pliers to remove the cable from the controller to avoid damaging the cable (see Figure 3).

or terminal from the controller maintenance port.
8. Disengage both retaining levers, remove the controller
containing the failed GLM from the enclosure, and place the controller on an antistatic bag or a grounded antistatic mat.
9. Unscrew the access door screw on top of the controller. 10. Remove the access door and set the door aside. 11. Disengage the GLM locking tabs that protrude through the
guide holes on the bottom side of the controller.
12. Operate the release lever on the exposed end of the GLM by
pressing the lower end of the release lever with your index finger while pulling the raised end up with your thumb.
13. Remove the GLM. Installing a GLM Use the following steps to install a GLM in single-controller configurations: Note: Before inserting the new GLM, locate the holes on the controller board where the GLM will reside. 1. Insert the new GLM by placing the GLM cable connection
end through the opening on controller front from the top.
2. Align the locking tab on the bottom of the replacement GLM
with the board guide holes, and press firmly to seat the GLM.
3. Press the release lever firmly into place to secure the GLM. 4. Install the access door on top of the controller, and then
secure the door with the screw.
5. Carefully align the controller in the appropriate guide rails.
Caution: Misalignment can damage the backplane.
6. Insert the controller and engage the retaining levers.
