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.

Warning: To avoid possible electrostatic damage to the module or panel, place it in a static-free bag or on a static-free surface.

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.

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.

Use the following TL1 command to download the firmware.
