Q3. What if I'm connecting from a single PC from an external office?

X-RAY STEP 1 - Connect to Cisco's' Virtual Private Network (VPN)

Communicating with a Cisco Easy VPN server, creates a secure connection over the Internet. Through this connection you can access X-Ray Associates' private network as if you were an on-site user.

Required Internet Settings

1. Log into your computer as the Administrator.
2. Ensure you are connected to the Internet.
3. Open Internet Explorer. Make sure you are running Internet Explorer 5.5-6.5 SP2 by going to Help at the top of the screen and selecting 'About Internet Explorer'. Close box by clicking OK. Next, go to Tools at the top of the screen and make sure Pop-Up Blocker is turned off.
4. At the top of your screen, go to Tools > Internet Options > Security tab > Custom Level and set Security Level for this Zone to MEDIUM and hit reset. ***
5. While still in Tools > Internet Options > Security tab, in the settings window, look for the Active X controls and Plug-ins section *:

- Set Automatic prompting for Active x controls = Enable
- Set Download signed Active X controls = Enable
- Set Run Active X controls and Plug-ins = Enable
- Set Script Active X controls marked safe for scripting = Enable

6. Close up boxes by clicking on ‘OK’. Click ‘YES’ to save changes.
7. Enter the following web address into Internet Explorer: http://24.244.218.194 and save as X-RAY STEP 1 in your  ’Favorites’. Another option is to simply click on X-RAY STEP 1 in the left hand column to connect you to our VPN.
8. You will be prompted for a username and password. Once your username and password are accepted, an SSL connection will be established.  Several boxes, including security information boxes, will pop up. Click ‘Yes’ or ’OK’ to all.

   You will know that you have successfully connected if you see a small yellow key in the lower right hand corner of your screen.

X-RAY STEP 2 - Connect to Centricity Web

9. You can now open Internet Explorer again and enter the following web address: http://10.1.0.19/amI. Save this address as X-RAY STEP 2 in your Favorites. Another option is to simply click the XRAY STEP 2 button in the left column to connect you to Cweb.
10. You will then login to Cweb with the personal username and password  provided to you by our Systems Administrator.
11. When you are finished using the Centricity Web and you wish to disconnect from VPN, simply right click on the small key in the lower right hand corner of your screen and select disconnect. The picture of the key will then disappear.
12. If you wish to reconnect to the VPN and Centricity Web, simply begin at step 7 or clicking on X-Ray Step 1 button to the left.

Q4. What if I'm connecting from a hospital or through a hospital network?

Please contact the hospital IT department for support for downloading Active X as you may require further permissions for downloading.

Q5. What if I'm connecting from an external physician's office and have already connected to York Central's Centricity Web from the same computer?

Active X controls have already been downloaded in order to use York Central Centricity Web so they do not need to be downloaded again.

Additional Information:

For security reasons, there is a 2 hour auto logout in the system for VPN access and 1 hour logout for Centricity Web access. For your convenience, 'split tunneling' feature allows one to connect to Internet while connected to our VPN tunnel.

Important Security Reassurance from GE Healthcare:

Users needs to lower Web browser's security to access Centricity web ONLY ONCE per PC. Once the Active X controls have been downloaded, the user may return to Internet options, Security, Custom Level and change their security settings if desired.
