3.
Swing the extractors forward to lock the board in place.
4. Observe the module and front-panel LEDs to determine whether the
FRE/FRE-2 module or SRM-F is functioning properly.
Following is a brief description of the LED activation sequence after you
insert a new FRE/FRE-2 or SRM-F module. (See the installation guide for the
module for a complete description of the LEDs.)
• When you insert a FRE/FRE-2 module, the DIAG LED turns on during
diagnostics and then turns off if diagnostics determine that the
FRE/FRE-2 is functional.
• If diagnostics determine that the FRE/FRE-2 is not functional, the DIAG
LED on the front panel and LED 8 on the FRE/FRE-2 module remain on.
If this occurs, ensure that the modules seat properly in the hardware
platform and issue the
diags command using the Bay Networks
Technician Interface.
• If diagnostics determine that the FRE/FRE-2 is functional and a link
module connects to the FRE/FRE-2, the hardware platform also performs
diagnostics on the link module.
Regardless of the results of the link module diagnostics, the BOOT LED
turns on, indicating that the FRE/FRE-2 is booting. If the link module or
any of its ports do not function, the link module Fail LED turns on.
5. Replace the board retainer bracket in a BLN or BLN-2 as follows:
a. Slide the top of the board retainer bracket into its designated ridge
and align the bottom of the bracket with the screw hole at the bottom
of the chassis (Figure 5-6 or Figure 5-7).
b. Using a screwdriver, secure the bracket to the chassis.
Note: Remove the module and repeat Steps 1 and 2 if the extractors do not
lock into place easily.
Note: Contact the Bay Networks Technical Response Center if the DIAG LED
does not turn off.
