Installing Mounting Ears and a Cabling Rack(s)
To facilitate installation and cable routing, mounting ears and a cabling rack are shipped together with
the S7900E series, but they are separated. Therefore, you first need to install the cabling rack on a
mounting ear.
For the S7906E-V, it is unnecessary to install cabling racks onto mounting ears. Two cabling racks are
provided for the S7906E-V: upward cabling rack and downward cabling rack. These two cabling racks
are different. The cabling rack with a tray should be installed in the lower part of the chassis. However,
they are installed in the same way.
The mounting ears of the S7900E series are installed in the same way.
