Replacing the fan in Broadcast Videohub or Enterprise Videohub
The Broadcast Videohub and Enterprise Videohub packages include a spare fan in case the pre-installed
fan stops working or becomes noisy. Videohub will continue to work even if the fan stops running.
However, a working fan will help to extend the life of the Videohub for many years and we recommend
the fan be replaced if it should ever stop running.
The fan is designed to be replaced without needing to switch off power to Videohub.
Step 1. Remove the four screws on the fan cover and lift up the cover gently.
Step 2. You will see the colored power cables connecting to a plug on Videohub. Gently remove the
plastic plug.
Step 3. Remove the two screws that attach the faulty fan to the fan cover.
Step 4. Replace the faulty fan with the spare fan by following this process in reverse. The spare fan
should immediately start running.
Tips for Connecting SDI cables
The weight of copper-based SDI cables quickly adds up so it is advisable to use your rack to support the
cables so that the full cable weight does not place undue stress on the BNC ports of your Videohub. This
is particularly important with larger models of Videohub due to the weight of many SDI cables. Tying
cable harnesses to the rack frame can provide support for large volumes of cabling.
It is also good practice to attach cables to the lowest BNC and optical fiber connectors first and then
work upwards. This will avoid having to push lots of cables out of the way as you attach more cables in
the future.
All Videohub models feature regular sized BNC ports, which make it easy to connect to other SDI
equipment using regular SDI cables.
If you're connecting Videohub to SDI equipment that has miniature SDI connectors, such as DIN 1.0/2.3,
we recommend using SDI cables that are terminated with a miniature connector at one end and a regular
BNC at the other. Alternatively, an adapter cable can be connected to a regular SDI cable but this could
prevent you from running long cables due to some loss of signal quality.
It’s easy to connect and disconnect SDI cables to and from your Videohub. However as you attach
more SDI cables, you might find it tricky to fit your fingers between the BNC connectors. You can use
an inexpensive BNC removal tool, from third party vendors, to help make this task easy even when your
Videohub has many cables connected.
