Eclipse Installation Manual
RAC combinations for
INUe
An INUe can be fitted with a maximum of:
• Five RAC 60s.
•Four RAC 6Xs.
(The reduced RAC numbers are to ensure temperature
limits within the INUe are not exceeded at high ambients.
See Node Card Maximums.)
DACs
DAC combinations DACs can be fitted singly or in combination to provide a mix
of interface types and capacities provided they have a
common backplane configuration. The backplane can be
set for 1.5 Mbps/DS1, 43 Mbps/DS3, or 155 Mbps/OC3.
TDM Mux DACs allow a mix of interfaces from a common
DS1 backplane configuration.
Increasing node capacity To achieve a greater node capacity, two or more INUs can
be interconnected via a DAC option.
DAC 16x Mini RJ-21trib
cable connector
Ensure correct orientation of the Mini RJ-21 connector on
DAC 16x before pushing it home. This can be checked by
the scalloped key to one side of the connector. Additionally,
a trib cable supplied by Aviat Networks will have the cable
exiting to the right side when viewed from the front.
Ensure the connector retaining screws are not
over-tightened - only use light/moderate screwdriver
pressure.
Line Protection (electrical
DACs)
Line (interface) protection can be provided for paired DS3
and STS3 electrical DACs.
Line Protection (optical
DACs)
Line (interface) protection can be provided for paired OC3
optical DACs.
General
Maximum Backplane
Capacity of Eclipse Node
The maximum drop, through plus drop, or through
backplane capacity on an Eclipse Node is one of the
following, depending on the backplane setting:
• 300 Mbps
• 128xDS1
•6xDS3
•2xOC3
Antistatic bags Enclose spare plug-ins, or plug-ins to be returned for
service, in an antistatic bag. When handling a plug-in to or
from an antistatic bag, do so at the INU/INUe and only
when you are connected to the INU/INUe via an ESD
ground strap.
Spare blank panels Keep any removed blanking panels for future use.
