CTP2000-Series Components

The following components make up CTP2000-series systems.

Power Supplies

The CTP2008 system has a single power supply, and the CTP2024 and CTP2056
systems have one supply with an option for a second hot-swappable power supply,
which provides redundancy. The green LED on the power supply front panel
indicates that the input power is OK; a red LED indicates a power supply fault. The
power supplies are interchangeable between the systems.
CAUTION:
fire, replace only with the same type and rating of fuse.
ATTENTION:
remplacer par un fusible de même type et de mêmes caractéristiques nominales.
CAUTION:
electrical installation for CTP2000 series models.
You can remove the power supply by first unscrewing the retaining screw in the
lower-left corner of the power supply panel. Next, press the red tab on the extractor
and pull the extractor lever outward. You can insert a power supply by first sliding
the power supply in with the extractor pulled outward. Then push the extractor
inward to latch the power supply in place, and tighten the retaining screw at the
lower-left corner of the supply.

Processor Module

This module provides the IP network connection through the 100/1000-Mbps
Ethernet interface (copper) or optional dual 100-Mbps and 1-Gbps fiber interfaces,
which are installed in the PMC1 slot. The primary connector is on the left when the
PMC1 slot is used. The PMC2 slot is not used. The processor module can be
installed only in the bottom slot of the CTP2008 model, and only in the upper slot
of the CTP2024 and CTP2056 models.
Remove or install the processor modules (front and rear) only with the unit power
turned off. Install the processor module by inserting it into the chassis with the
extractors unlocked and pushed outward. When you insert the module into the
backplane connector, the extractors are pushed inward to insert the module into the
connectors. The module has two screws, which you use to lock the processor
module into the chassis. Loosen the screws to remove the module. Then push the
extractors outward while depressing the red latch.
The processor module provides a front connector for asynchronous console, video,
and keyboard connections, but you must use a special cable that is provided with
the system. Never leave the cable installed in the unit when the cable is not in use.
A ferrite core should be connected to any Ethernet cable that is connected to the
processor. We recommend the Fair-Rite Products 461164281.
