ATTENTION
Note the following considerations:
• Note 1:
– Data 3 and Data 4 cables may be run in a common tray but should be
separated by a barrier. This barrier does not have to be grounded.
• Note 2:
– Data 1 and Data 2 cables may be in a common tray, provided they are
separated by a grounded steel barrier.
