SLSC-12001 Chassis Getting Started Guide and Specifications
The SLSC-12001 chassis can draw a significant current from the +24 V power input to support
module requirements. Refer to the
Physical Characteristics
section for wire gauge sizes
permitted by the SLSC-12001 chassis connector when wiring the power. Minimize the cable
length between the power supply and SLSC-12001 chassis. Avoid unnecessary intermediate
connections on the power lines. If possible, direct wiring between the power supply and chassis
is preferred.
Complete the following steps to connect the external power supply:
1.
Ensure the +24 V external power supply is powered off.
2.
Wire the power supply to the SLSC-12001 chassis power input connector, which is shipped
with the SLSC-12001 chassis. Refer to the
Physical Characteristics
section for wire gauge
information. Refer to Table 1 for signal connection information.
3.
Install the power connector on the rear of the SLSC-12001 chassis and secure it with the
locking tabs.
Note
If a source with remote sensing is used, connect the sensing wires as close
as possible to the chassis power input connector.
Powering on the Chassis
The SLSC-12001 chassis does not have an on/off switch since an external power supply
provides power to the SLSC-12001 chassis. Connecting an already powered on 24 V supply
to the SLSC-12001 is allowed, but higher transient currents may be involved.
When you apply power to the SLSC-12001, the chassis fans start and the POWER LED should
turn green immediately. When the POWER LED and the STATUS LED are both green, the
chassis is ready for host communication. Refer to the
Understanding LED Indicators
section
to identify other LED indications.
Note
Ensure that SLSC modules are installed in the chassis prior to power-up.
