Verilink 1051-2 Chassis (CG) Configuration/Installation Gui Manuel d'utilisateur télécharger pdf

The Verilink 1051-2 chassis holds up to

twelve of the following modules:

2000 ESF CSU 3021 E1 NTU

2010 ESF CSU 4001 DDS CSU/DSU

2048 PMU/NTU 4010 DDS CSU/DSU

2100 CSU 4051 DDS CSU/DSU

3001 CSU/DSU 8100A Site Controller

Each module attaches to the chassis back-

plane board through two connectors. With

these connectors, each module receives −48

VDC power and exchanges control and input/

output signals. The chassis contains no active

components.

Power Connections

The chassis is designed with two power buses

connected to TB2. The A bus feeds the odd

slots (1, 3, 5, 7, 9, and 11). The B bus feeds

the even slots (2, 4, 6, 8, 10, and 12). Connect

a Frame Ground lead (18- to 20-gauge) to

pin 2 before applying power to the unit. Con-

nect the other end of this lead to an appropri-

ate frame ground.

Redundant Power Source: A power

board is factory installed on TB2 allowing the

connection of two independent −48 VDC

supplies operating in a redundant mode. All

slots are powered from the combined input of

the A and B power supplies. If one supply

fails, the other powers the entire chassis.

To operate in the redundant mode, connect

pins 3 and 4 (−48 V IN) on the redundant

power board to the negative (−) terminal of

the power supply. Connect pins 1 and 6 (+48

V RTN) to the positive (+) terminal of the

power supply.

Single Power Source: When using a sin-

gle power source, connect the A bus termi-

nals (pins 4 and 6) on the redundant power

board to the corresponding terminals of the

power supply.

If the redundant power board is not used, the

A bus and B bus must be connected together

with a jumper (pin 3 to pin 4 and pin 1 to

pin 6).

Dual Power Source: When using dual in-

dependent 48 VDC power supplies, one

source feeds the A bus while another source

feeds the B bus. First, remove the redundant

power board. Connect the A bus (pins 4 and

6) to the corresponding terminals of power

supply A (to power the odd numbered slots).

Connect the B bus (pins 1 and 3) to the corre-

sponding terminals of power supply B (to

power the even numbered slots).

The maximum current draw of a fully loaded

chassis is two amperes. The Verilink 1040

and 1041 power shelves can supply a maxi-

mum of two amps. Ensure that the proper fuse

size is used.
