Replacing the Clock Module
This example shows how to check the status of the clock module on a Cisco 7600 series router running
Cisco IOS software:
Router> show environment status
backplane:
operating clock count:2
fan-tray 1:
fan-tray 1 fan-fail:OK
clock 1:
clock 1 OK:not OK, clock 1 clock-inuse:not-in-use
clock 2:
clock 2 OK:OK, clock 2 clock-inuse:in-use
...
Router>
The above example shows a failure with clock 1 (clock module A).
Note
Clock module A refers to clock 1 and clock module B refers to clock 2.
Note
The clock module on a Cisco 7609 router or on a Catalyst 6509-NEBS-A switch contains dual
redundant clocks (clock 1 and clock 2) on one module.
Replacing the Clock Module
Note
Warning
You must remove all power from the Cisco 7600 series router before replacing the clock module.
This unit might have more than one power supply connection. All connections must be removed to
de-energize the unit.
The clock module is installed as follows:
•
Behind power supply 1 (the lower power supply) on the Cisco 7603 router or Catalyst 6503 switch
(see Figure 1)
•
Behind power supply 1 (the lower power supply) on the Cisco 7604 router or Catalyst 6504 switch
(see Figure 2)
•
Behind power supply 2 (the upper power supply) for the Cisco 7606 router (see Figure 3)
•
At the rear of the cabinet (the upper half) on the Cisco 7609 router or Catalyst 6509-NEBS-A switch
(see Figure 4)

Replacing the Clock Module on a Cisco 7603 Router, a Cisco 7604 Router, a
Cisco 7606 Router, a Catalyst 6503 Switch, or a Catalyst 6504 Switch
To replace the clock module on a Cisco 7603 router, a Cisco 7604 router, a Cisco 7606 router, a Catalyst
6503 switch or a Catalyst 6504 switch, perform these steps:

Replacing the Clock Module
Step 1
Step 2
Power down the router as follows:
a.
For a DC power supply, power down the router, verify that power is off to the DC circuit connected
to the power supply, and remove the power supply. (Refer to Chapter 5, “Removal and Replacement
Procedures,” in the Cisco 7600 Series Router Installation Guide, or refer to Chapter 4, “Removal
and Replacement Procedures,” in the Catalyst 6500 Series Switches Installation Guide.)
b.
For an AC power supply, disconnect the power cord from the power source, and remove the power
supply. Do not touch the metal prongs on the power cord when it is still connected to the power
supply. (Refer to Chapter 5, “Removal and Replacement Procedures,” in the Cisco 7600 Series
Router Installation Guide, or refer to Chapter 4, “Removal and Replacement Procedures,” in the
Catalyst 6500 Series Switches Installation Guide.)
Locate the clock module. (See Figure 1 for Cisco 7603 router and Catalyst 6503 switch, Figure 2 for a
Cisco 7604 router and Catalyst 6504 switch, and Figure 3 for the Cisco 7606 router.
Note
Note the position of the clock module before you remove it from the chassis because you
must install the new clock module in the same position.
Step 3
Remove the three securing screws that secure the clock module.
Step 4
Carefully lift and remove the clock module, placing it on an antistatic mat or foam.
Step 5
Remove the new clock module from the antistatic bag.
Step 6
Hold the clock module with the plug away from you.
Step 7
Carefully press the clock module onto the connector.
Step 8
Replace the three securing screws.
Step 9
Install the power supply. (Refer to Chapter 5, “Removal and Replacement Procedures,” in the Cisco
7600 Series Router Installation Guide, or refer to Chapter 4, “Removal and Replacement Procedures,”
in the Catalyst 6500 Series Switches Installation Guide.)
Replacing the Clock Module on a Cisco 7609 Router or a Catalyst 6509-NEBS-A
Switch
To replace the clock module on a Cisco 7609 router or a Catalyst 6509-NEBS-A switch, perform these
steps:
Step 1

Procedures,” in the Cisco 7600 Series Router Installation Guide, or refer to Chapter 4, “Removal
and Replacement Procedures,” in the Catalyst 6500 Series Switches Installation Guide.)
b.
For an AC power supply, disconnect the power cord from the power source. Do not touch the metal
prongs on the power cord when it is still connected to the power supply or power entry module
(PEM). (Refer to Chapter 5, “Removal and Replacement Procedures,” in the Cisco 7600 Series
Router Installation Guide, or refer to Chapter 4, “Removal and Replacement Procedures,” in the
Catalyst 6500 Series Switches Installation Guide.)

Verifying the Installation
Step 2
Locate the clock module. (See Figure 4 for the Cisco 7609 router and Catalyst 6509-NEBS-A switch.)
Note
Note the position of the clock module before you remove it from the chassis because you
must install the new clock module in the same position.
Step 3
Remove the three securing screws that secure the clock module.
Step 4
Carefully lift and remove the clock module, placing it on an antistatic mat or foam.
Step 5
Remove the new clock module from the antistatic bag.
Step 6
Hold the clock module with the plug away from you.
Step 7
Carefully press the clock module onto the connector.
Step 8
Replace the three securing screws.
Step 9
Reconnect power to the supply. (Refer to Chapter 5, “Removal and Replacement Procedures,” in the
Cisco 7600 Series Router Installation Guide, or refer to Chapter 4, “Removal and Replacement
Procedures,” in the Catalyst 6500 Series Switches Installation Guide.)
Verifying the Installation
To verify the status of the clock module, perform these steps:
Step 1
Power up the router or switch.
Step 2
From the EXEC prompt (Router>), enter enable to enter privileged EXEC mode.
Step 3
Enter the password assigned to the system.
Step 4
Enter the show environment status command to verify the status of the replaced clock module.
This example shows that the clock module is functioning properly:
Router> enable
Password:
Router#
Router> show environment status
backplane:
operating clock count:2
fan-tray 1:
fan-tray 1 fan-fail:OK
clock 1:
clock 1 OK:OK, clock 1 clock-inuse:in-use
clock 2:
clock 2 OK:OK, clock 2 clock-inuse:not-in-use
...
Router>
Note
Clock module A refers to clock 1 and clock module B refers to clock 2.
