Repairing the TimeProvider
Repairing the TimeProvider
Repairing the TimeProvider is limited to replacing cards. Refer to Working With
Cards , on page 82, for information on how to properly handle cards and modules to
prevent electrostatic or physical damage.
To remove an IOC, loosen the captive screws and lift the removal tabs on each side
of the card, then slide the module out of the shelf. To remove the IMC, loosen the
captive screws and pull the module out of the shelf using the U-shaped handle on
the front panel. Place the module on an anti-static surface or in an anti-static bag.
To remove an Input or Output module, loosen the captive screws and then pull the
module using the captive screw. Place the module on an anti-static surface or in an
anti-static bag.

Upgrading the Firmware
You can upgrade the firmware in the IMC or IOC using TL1 commands and software
available from Symmetricom. Only users with Admin-level or Security-level access
can execute the command. The command places the management module in the
firmware download mode and terminates all sessions except the session performing
the upgrade. During the upgrade process, no new sessions are allowed. Refer to
the TL1 Reference Guide for details on the upgrade process.
Use the following TL1 command to download the firmware.
Warning: To avoid possible electrostatic damage to the module
or panel, place it in a static-free bag or on a static-free surface.
Caution: To avoid a possible service call, do not issue any additional
TL1 commands to the TimeProvider, do not remove power from the
TimeProvider, and do not remove an IOC or IMC from the shelf during
the firmware upgrade process (minimum 30 minutes). Doing so could
corrupt the flash memory in a card, disabling the TimeProvider.
