Follow applicable health and safety rules for use of silicone grease. If necessary
use the latex gloves supplied with the products.
If upgrading an unprotected link to 1+1 Hot Standby, mute the active unit before
installing the coupler. For safety reasons this is required when working with the
ODUs or when working close to the antenna. See Disabling and enabling the
wireless interface on page 7-32.
When installing 1+1 Hot Standby links, observe that the ODUs are labeled ‘Hi’ or ‘Lo’
depending on the frequency sub-band. Install the two ‘Hi’ ODUs at one end of the link
and the two ‘Lo’ ODUs at the other end.
Installing a direct mount antenna with one ODU
In the direct mount configuration, attach the ODU directly to the antenna (with Cambium
ODU interface) via four latches.
To install a direct mount antenna with a single ODU, proceed as follows:
1
Follow the antenna manufacturer’s instructions to attach the antenna to its bracket.
2
Polarization depends upon the antenna waveguide interface position. To change
polarization, rotate the antenna transition, following the antenna manufacturer’s
instructions.
