Repairing the TimeProvider 5000
1. Attach a wrist grounding strap and connect it to the TimeProvider 5000 chassis.
2. Remove the IOC module using the procedure above.
3. Align the new IOC module’s edges within the guides of the selected slot.
4. Slide the IOC module into the chassis and press firmly until it seats fully into its
backplane edge connector.
5. Tighten the captive screws located on each side of the panel
6. Copy the contents of the IOC memory stored in the IMC by issuing the following
command.
Type
set configuration restore ioc and press Enter.
If you have not stored the contents of the IOC memory in the IMC, then provision
the IOC using the procedures and commands described in Chapter 4, Provisioning.
4. Wait for the IOC to reboot and achieve normal operating state.
Replacing One of Two IOCs In a Chassis
Ensure that the IOC card that is to be replaced is the standby card before removing
it.
For this example, assume that IOC1 is the card that is to be replaced, and that it is the active
card. Therefore, IOC2 is the standby card. This example demonstrates switching IOC2 to be
the active card, then using the “show ioc-state” command to verify the switch.
1. Attach a wrist grounding strap and connect it to the TimeProvider 5000 chassis.
2. Type
set ioc-state ioc2 active and press Enter.
3. Type
show ioc-state and press Enter to verify that the standby card has been
switched to active.
4. Loosen the screws and then pull out the IOC. Be sure to place the IOC on a
static-free surface.
Note: Removing the active card is not recommended. Before
removing the active card, manually switch the active IOC card
to standby using steps 2 and 3 in the procedure below.
Note: Switchover to the standby IOC will be prohibited if the
standby IOC has alarms of higher severity than the active IOC
or if the standby IOC is still in warm-up. Check system status
and alarms if the command fails.
