Eclipse Installation Manual
When installed in an INUe, the INUe must be fitted with the 2RU FAN module as it
provides almost double the air flow of two 1RU FAN modules.
The PCC should always be installed next to the FAN card to get best air flow cooling.
The PCC must be connected to the NCC before applying power to the PCC to avoid a
current-inrush trip (overload) on the PCC.
The PCC can be plugged into any INU/INUe option slot. It is not connected to the
backplane and is its function is not monitored within Portal.
Where an NPC is fitted, two PCCs are required for +24 Vdc operation, one for the
NCC, the other for the NPC. This means an INUe must be used for NCC + NPC
operation.
If the PCC front-panel LED is not lit, it indicates the existence of abnormal
conditions such as output under-voltage, output over-voltage, loss of input power,
output over-current, or open input fuse.
Power Cables
The INU power cable is included in the IDC Installation Kit. It is supplied with a D-sub
M/F 2W2 connector fitted at one end and wire at the other. The cable is nominally 5 m
(16 ft), and the wires are 4 mm
2
(AWG 12).
The cable is used for -48 Vdc connections to an NCC or NPC, or for +24 Vdc
connections to a PCC.
The blue wire must be connected to live (-48 Vdc or +24 Vdc); the black wire to ground
(+48 Vdc or -24 Vdc).
Figure 6-4. Power Cable and Connector
DC power connector can be shorted inadvertently if applied at an angle.
Always insert with correct alignment.
The PCC is supplied with a power cable to connect to an NCC or NPC.
Similarly, the power line filter unit is supplied with a power cable to connect to an NCC,
NPC, or PCC.
