Instruction Manual – Enova DGX 8/16/32/64 Digital Media Switchers
Attaching Cables
Important:
Before attaching cables, be sure to set the DXLink Fiber unit’s DIP switch toggles if necessary
(see the “Instruction Manual – DXLink Fiber, Duplex Transmitters and Receivers”).
OSHA Directive
The
OSHA Technical Manual
(at https://www.osha.gov/dts/osta/otm/otm_iii/otm_iii_6.html) under “VI. Control
Measures and Safety Programs” states: “Direct exposure on the eye by a beam of laser light should
always
be avoided
with any laser,
no matter how low the power
.”
For the Enova DGX 8/16/32 – Viewed from the rear of the enclosure, input boards (for attaching sources) are on the left,
and output boards (for attaching destinations) are on the right. For the Enova DGX 64, see description following.
Enova DGX 8/16
– Input and output channel numbers correspond to the connectors and are located between the input
and output boards. For inputs, numbering is consecutive from left to right on each board from the top board to the bottom
one; outputs start over at “1” and follow the same pattern.
Enova DGX 32
– Input and output channel numbers correspond to the connectors and are located on the numbering
plate (metal strip) directly above the boards. For inputs, numbering is consecutive from top to bottom on each board
from the left board to the right one; outputs start over at “1” and follow the same pattern.
Enova DGX 64
–
Input and output channel numbers correspond to the connectors and are located in the middle of
the enclosure between boards on either side. For inputs, numbering is consecutive from left to right on each board
from the top input board on the left to the lowest input board on the left, continuing on the top input board on the
right to the lowest input board on the right.
Outputs are in the lower part of the enclosure, start over at “1” on the left,
and follow the same pattern as the inputs.
Note:
Instructions for attaching cable management bars are on page 39. These bars are recommended and
provided with each DXLink Fiber Board.
DXLink Fiber Optic Cable Requirements
Fiber optic cables used between separate buildings
The cable must be rugged enough to endure the rigors of installation, environmental conditions
(e.g., heat, cold, moisture), and comply with TIA/EIA-568-B.3 standard ICEAA-640.
Fiber optic cables used within a common building*
The cable must comply with the general requirements of TIA/EIA-568-B.1.
* “Common building” is defined as: Where the walls of the structure(s) are physically connected and the structure(s)
share a single ground reference.
Transceiver Types / Cable Types / Cable Runs
The type of SFP+ fiber optic transceiver helps determine the maximum length of cable runs possible. Cable quality is
also a determining factor.
Warning:
DXLink Fiber units use laser transceivers, which are Class 1 Eye Safe per IEC 60825-1/CDRH
requirements. While the Class 1 category indicates that the invisible laser used is safe, we recommend
avoiding direct eye exposure when using any optical fiber products (see the OSHA directive below).
OSHA Directive
Caution:
Do not severely bend or kink the fiber optic cable. Irreversible damage can occur. Refer to the
physical limitations (bend radius) specified for the cable.
