Before access rights to I/O from 
consoles can be restricted, and 
before port patching can be carried 
out using H2O, I/O ports need to be 
added to folders. Folders are a means 
of organizing ports into lists and sub-
lists.
Organizing Folders
The right hand pane shows the folder 
structure and the ports within those 
folders. Figure 1 shows an example 
viewing the contents of a folder labelled 
“IO 1”. 
Click FOLDERS ‘+’ at the bottom of the 
screen to add a new folder. Note, folders 
can be created within folders to help give 
a logical structure relating to location and 
usage. 
When managing access rights to I/O 
from consoles, whole folders can be 
selected which in turn selects all the 
ports within that folder, or its subfolders. 
Therefore the folder structure created 
should minimize the number of clicks 
required to change access for common 
situations. For example, if there is a folder 
called “Studio1” which contains folders 
called “Area1” & “Area2”, Access to 
Studio1 can be completely restricted or 
enabled by selecting the “Studio1” folder, 
or to the individual areas by clicking on 
the sub-folders. Flexibility is maintained 
by allowing ports to be selected on an 
individual basis if required.
The FOLDERS ‘-’ button can be used to 
remove folders that are no longer needed, 
and the FOLDERS EDIT button can be 
used to re-label folders if required.
Adding Ports to Folders
A folder may contain other folders or I/O 
ports, however it cannot contain both. 
Ports may only be added to folders or 
sub-folders which do not contain further 
sub-folders.

The Manage Folders page shows the 
available I/O boxes in the left hand pane. 
Clicking on a box brings up a list of all the 
ports within that box. Clicking the BOXES 
button at the top of the list reverts to the 
list of I/O boxes. Column headers can 
be clicked to view the lists in a different 
order. The PORT DESCRIPTIONS button 
displays the additional descriptive label for 
the ports.
To add ports to a folder, select the relevant 
I/O box on the left, then select the port 
or ports required. Ports are selected by 
clicking on them. To select multiple ports, 
hold CTRL whilst clicking each required 
port, or to select a consecutive group 
of ports, hold SHIFT whilst clicking on 
the second to highlight all the ports in 
between. Highlight the folder chosen to 
be the location of the ports and click the 
‘Add to Folder’ button at the bottom of the 
folder list, shown in Figure 2, to add the 
selected ports to the selected folder. To 
remove ports from a folder, highlight the
