Cabling Requirements
Storage
To store an uninstalled 7705 SAR-A, repackage it in its original packaging or an
appropriately sized container and keep it in a dry, dust-free, temperature-controlled
environment.
Table 8 lists the storage specifications.
Warning:
• To meet surge protection requirements, the shield on any open-ended cable must be
grounded by attaching the shield to a convenient chassis ground point, using hardware
suitable to provide a solid electrical and mechanical connection. In addition, ensure that
there is sufficient strain relief to remove any mechanical strain on the ground connection
due to cable movement.
• The intra-building port(s) of the equipment or sub-assembly is suitable for connection to
intra-building or unexposed wiring or cabling only. The intra-building port(s) of the
equipment or sub-assembly must not be metallically connected to interfaces that
connect to the Outside Plant (OSP) or its wiring. These interfaces are designed for use
as intra-building interfaces only (Type 2 ports as described in GR-1089-CORE) and
require isolation from the exposed OSP cabling. The addition of primary protectors is
not sufficient protection in order to connect these interfaces metallically to OSP wiring.
Connection to external OSP wiring must be made through an external CSU prior to
exiting the building.
• Bare conductors must be coated with an appropriate antioxidant compound before
crimp connections are made. All unplated connectors, braided straps, and bus bars
must be brought to a bright finish and then coated with an antioxidant before they are
connected.
• The 7705 SAR-A is suitable for use in DC-I, DC-C, or AC powered installations. There
are no connections between battery return and the chassis ground within the
7705 SAR-A.
• The Ethernet and T1/E1 electrical ports on the 7705 SAR-A are SELV ports and have
not been designed or tested to comply with the AC power cross-requirements of
Telcordia GR-1089-CORE, Type 4 ports. If a 7705 SAR-A is deployed in Type 4
installations, the Ethernet and T1/E1 shielded electrical cables must be routed to avoid
parallel runs and any possible contact with AC power conductors.
