Connecting the Power Supply Duplication Cable between Two Cages
An H719 DC-D connection cable enables the PS19 DC-D to supply power to two
adjacent cages with or without redundancy. The H719 DC-D cable must be ordered
separately by the customer.
The following two configurations are possible when the connection cable is used:
Configuration
Economical
Redundant
Connecting the POWER SUPPLY DUPLICATION connector (located on the cage rear
panel) for PS19 DC or PS19 AC power supplies will result in damage to the system.
This connector is only used with the PS19 DC-D power supply. Do not use this
connector when the PS19 DC or PS19 AC power supplies are installed.
Tip:
Using H719 cable requires 30A/125V slow blow fuse on the cage rear panel.
In old versions of the Coral IPx systems replace the 15A/125V S.B. fuse with
a 30A/125V S.B. fuse.
Description
One PS19 DC-D can supply power to two adjacent cages
by connecting an H719 DC-D cable from the backplane
of the one cage to the POWER SUPPLY
DUPLICATION connector on the adjacent cage. See
.
Figure 7-7
One PS19 DC-D can be installed on each of two adjacent
cages to provide power supply redundancy. An H719
DC-D cable is connected between both cages, in the
same manner as above. In this type of configuration, if
one of the power supplies fail, the other unit supplies
power to both cages and no calls are lost. This
configuration is depicted in .
