iRM4451nn00-2 iRRH Product Description and Installation Guide 4-3
4.2 Required site equipment
This section describes the additional interconnecting equipment required for the
installation of the Altiostar Networks iRM4451nn00-2. These are essentially cables,
connectors and fixing arrangements. The specification of these items may need to be
customized on site by the Installer (specifically the type and length of cables). Refer
to Table 3-2 when ordering and customizing the following items:
• Grounding cable between the iRRH and the local grounding point. Altiostar
Networks provides the two-hole lug for crimping onto the cable.
• Power cable between the iRRH and local DC supply. Installer must provide suitable
lightning and surge suppression devices on the power line to the unit (minimum
20 kA-rated device recommended). We recommend one lightning and surge
suppressor be installed close to the iRRH on the tower/pole/wall and one on the
cable entrance just before it enters the facility.
• Optical fiber cables between iRRH and transport network.
Other than lightning and surge suppression devices, Table 4-2 provides a list of the
Installer-supplied interconnection equipment required to install the iRM4451nn00-2.
NOTE
Some parts have an order lead-time of up to 10 weeks. It is important that
these items be ordered as soon as possible in the planning phases of the iRRH
installation so that they are available on-site at the time of installation.
