Full reset procedure
Issue: Version 1.2 - File:T:\Product\XT Series Server\Tech Info\SDTI\XHub full reset 061124.txt

This procedure describes how to totally reset an XHub. It is used for the production of the XHubs. 
If during an upgrade of the XHub, a communication problem occurs, the XHub can become unusable. This full reset procedure reloads the necessary software on the XHub to make it operational again.

Please identify first the XHub version required and the XHub type.
There are 2 types of hardware for XHub:
- XHub 540Mbps : can be used with XNet network at 270 and 540Mbps
- XHub 1.5Gbps (XHub[2]) : can be used with XNet and XNet[2] networks at 270, 540 and 1485Mbps. There is a sticker at the back those mentioning XHub[2]

There are 3 current software versions for XHub :
-	v. 1.07, compatible with Multicam 5.xx.xx and 6.xx.xx
-	v. 2.05, compatible with Multicam 7.xx.xx or later for XHub 540Mbps
-	v. 2.06, compatible with Multicam 7.xx.xx or later for XHub 1.5 Gbps
	
Identify the current version of XHub
1. Turn off the XHub
2. Move down all 4 dip switches located on the left side of the BNC connectors
3. Turn on the XHub
4. The branch status LEDs show the software version in a binary pattern :

Branch LED #	1			2			3			4			5			6			7
 	 	 	 	 	 	 	 
v. 1.06	 						green	red	 				green	green	 
v. 1.07	 						green	red	 				green	green	green
v. 2.03				green	 			red	 	 						green	green
v. 2.04				green	 			red	 				green	 	 
v. 2.05       green       red         green       green
v. 2.06				green				red					green	green	

5. To return the XHub to its normal operational mode : turn it off, move the 4 dip switches up, turn on the XHub

Identify the XHub type
	The SPEED led helps identifying the XHub Type :
1. If the SPEED led is OFF then the XHub Type is 540 Mbps
