Before you begin

Icon for electrostatic discharge wrist strap Use approved ESD procedures to prevent damage.

Attention:

This procedure is not a stand-alone procedure. Customer disruption and damage to the hardware might occur when microcode and power boundaries are not in the proper conditions for this service action.
If a serviceable event FRU repair directed you to this procedure, the microcode and power boundaries are already set.
If a serviceable event FRU repair did not direct you to this procedure, see MAP1230 Replace a FRU without using a serviceable event.

Notes:

All the cables and FRUs to be removed must be uniquely identified so they can be reinstalled correctly.
If an installed earthquake resistance kit prevents you from accessing this FRU, refer to MAP1600.

The laptop DC power adapter (used within the rack) or laptop AC power adapter (used for external management console installed within a customer-provided rack) has the following:
- A permanently connected output DC cable that goes to the rear connector on the laptop unit. The cable passes through the laptop rotating tray assembly.
- A modular power input cable that can be disconnected from the power adapter.

Test the laptop to ensure all connections are functioning:
1. Use the network topology tool to ensure the gray and black private network connections are functioning. Refer to MAP7001 Using the network topology tool.
2. Display open serviceable events that need repair. If there are serviceable events related to this HMC or private network timeout problems created before or during the time you replaced this laptop, close them now.
3. Run the storage facility status (end of call) option. Refer to MAP1100 View storage facility state (end of call).
4. If the customer allows a phone line connection, test the modem.
  Select Service Management > Manage Outbound Connectivity > Configure > Local Modem > Test
5. If the customer allows VPN connections, test the connection.
  Select Service Management > Manage Outbound Connectivity > Internet VPN > Test
  
  If the test fails, go to MAP1301 Isolating Call Home/remote services failure
6. Ask the customer to test the access of the application or method that they will use to connect to the DS8000® Storage Manager in the management console.
This completes the procedure.
