+== How to switch On/Off the nodes of a Testbed ==
+
+If you have not done so yet: 
+
+ * [http://www.orbit-lab.org/wiki/Registration Register] for an account
+ * [https://www.orbit-lab.org/schedule/ Make a reservation] on the Schedular for a given tesbed
+
+Lets assume that you registered as user 'bob' and made a reservation for the 'grid' testbed. You then access the 'grid' console using the command:
+
+ {{{
+  ssh bob@console.grid.orbit-lab.org
+ }}}
+
+Then, to switch some nodes On/Off on the 'grid' testbed, use the command:
+
+ {{{
+  tellnode on all
+  # will turn On the entire set of 20x20 nodes on the 'grid'
+  
+  tellnode offs [[3,1],[5,6],[1,1..2]] 
+  # will turn Off (soft) the nodes 3,1 and 5,6 and 1,1 and 1,2
+
+  tellnode offh system:topo:circle 
+  # will turn Off (hard) the nodes in the topology file 'repository/system/topo/circle.rb'
+
+  tellnode on mytopo 
+  # will turn On the nodes in the topology file './mytopo.rb'
+ }}}
+
+The complete available option/commands for ''statnode'' are:
+
+ {{{
+tellnode --help
+
+Switch ON/OFF the nodes in a testbed
+Usage:
+      tellnode [-h]
+      tellnode [COMMAND] [TOPOLOGY] [DOMAIN]
+ 
+      With: 
+      -h, --help    print this help message
+ 
+      COMMAND:
+      on, -on, --turn-on              turn node(s) ON
+      offs, -offs, --turn-off-soft    turn node(s) OFF (soft)
+      offh, -offh, --turn-off-hard    turn node(s) OFF (hard)
+ 
+      TOPOLOGY      a valid topology description or file
+                    (default is the entire set of nodes on the default testbed)
+ 
+      Some Examples: 
+                    tellnode on all grid
+                    tellnode on 1,1..2
+                    tellnode offs [[1,2],[1,1]] sb1 
+                    tellnode offs [[1,1],[2..6,1..2]] 
+                    tellnode offh system:topo:all
+                    tellnode offh topo_grid_active
+ }}}
