A-4 Appendix A - ELMo 120 Multiplexer installation requirements
Revision 2.01 ELMo 120 Multiplexer Installation and Maintenance Guide 08-01023-01
CBN grounding environment
In most facilities using the CBN environment, the bay containing the ELMo
120 shelf should be grounded to a frame ground bar (FGB) as the common
ground point using a 6 AWG, stranded, ground conductor. In smaller facilities
where no FGB exists, the building principal ground (BPG) must be used.
If the facility has a ground collector, the bay must be grounded to the connector
using a 6 AWG (stranded) ground conductor to the collector. The collector
must then be grounded to the common ground point (FGB or BPG) using a 2
AWG (stranded) ground conductor.
If the distance from the FGB, BPG or ground collector is greater than
53 ft (16 m), a 2 AWG (stranded) ground conductor must be used to ground the
bay.
IBN grounding environment
In most facilities using the IBN environment, the bay containing the ELMo
120 shelf should be grounded using a 6 AWG, stranded, ground conductor to
the building single-point ground (SPG) as the common ground point. In
smaller facilities where no SPG exists, the building principal ground (BPG)
must be used.
If the facility has a ground collector, the bay must be grounded to the connector
using a 6 AWG (stranded) ground conductor to the collector. The collector
must then be grounded to the common ground point (SPG or BPG) using a 2
AWG (stranded) ground conductor.
If the distance from the SPG, BPG or ground collector is greater than
53 ft (16 m), a 2 AWG (stranded) ground conductor must be used to ground the
bay.
Network support equipment
The network support equipment that may need to be installed includes the
following:
•
Ethernet 10Base-T hub port for ELMo 120 Hub card connection (one per
ELMo 120 shelf)
• Ethernet 10Base-T hub ports for NSS/InterProxy (two per NSS)
• LAN router connections
• WAN gateway connection
Network support requirements will vary according to the existing facility
resources. See the completed Elastic Networks Site Survey Questionnaire for
more information.
