2. If Application software is up, perform{ctuser@hostname}cleanMon.

3. In the Unix Shell, become root:

   {ctuser@ hostname }   su  -

4. Password: <password>

   note:

   If the Password has not been modified by the site and is not known, contact Local GE Service.

5. Perform the following steps to install the Service Pack CD:

   1. [root@ hostname ]# start_udev

   2. A message will return: OK

   3. Wait 15 seconds after the OK is returned, then type the following install script:

      [root@ hostname ]# patch_install -c

      note:

      If the Service Pack fails to install, perform [root@hostname]#start_udev. Wait 15 seconds after OK, then retry the Service Pack.

      Any patches on the Service Pack CD will be listed. Before installation of each patch, the window will wait for user's confirmation as follows:

      I will install update Patch Name , is this ok ? [y/n]

   4. Input y to install this patch.

      note:

      Service Pack CDs will include any new patches and all older patches that are still applicable. Load all the patches included in the latest Service Pack CD.

   5. After installing the Service Pack CD, type patch_status (Class M service key inserted is required to use this command) in the Shell window to determine which Service Pack patches were installed (if any). The following is an alternate command to verify the Service Pack load:

      [root@ hostname ]# showprods | grep  -i ServicePack

   6. Type:[root@hostname]#reboot

      note:

      A reboot is always required after a patch is installed. Additional processes may be required for installing certain Service Pack media. Refer to the instructions sent with the Service Pack.

If HIPAA is turned ON, then configure it now. (Refer to HIPAA Configuration) When HIPAA configuration is complete, return to this procedure.

For general information on Product Network Filters, please see Product Network Filter Theory.

If your customer has special network requirements, then proceed to Configure Product Network Filters now. When PNF configuration is complete, return to this procedure.

If the site requires the configuration of AW Direct Connect, then configure it now (see AW Direct Connect). When configuration is complete, return to this procedure.

notice NEVER Use CTRL - ALT - DELETE to reboot the host computer. This technique will NOT reboot all console subsystems, and as such is an unacceptable practice.

To restart the system:

1. Replace the Hospital Backbone Ethernet cable to the Console Bulkhead Assembly (located at the rear of the Operator Console).

2. Open a Unix shell and type the following:

   {ctuser@ hostname }   sync

   {ctuser@ hostname }   sync

   {ctuser@ hostname }   reboot

When the system comes up the following screen will be displayed if HIPAA Present was set to On during the LOAD process. Verify the admin screen below has the following 'Select user':

• Select user: root

• Password: #bigguy
