Overview
The Model 1002 Universal Chassis System (UCS) Chassis houses and supplies power to Canoga
Perkins modules that are 2U high. The UCS 1002 can be part of a managed domain of up to eight
chassis; these can be a mix of UCS 1000 and UCS 1002. Figure 1 shows the UCS 1002 with
these components:
• Chassis Interconnect Module (CIM), required in slot 0, provides alarm relays, connection to
other chassis in the domain, and management through the chassis backplane; for details, see
the Model 1202 Chassis Interconnect Module User Manual
• Domain Management Module (DMM), optional and recommended in slot 1, provides
management for all chassis in the domain through a single IP addressable user interface
screen; for details, see the Model 1502 Domain Management Module User Manual (or the
Model 1500 Domain Management Module User Manual when the DMM is installed in the
UCS 1000)
• Application modules, located in any slot from 1 through 14, such as fiber optic modems,
multiplexers, or media converters
• Power Supply, can be one or two AC or DC supplies, or an AC supply and a DC supply;
place the primary supply in slot 15 and the secondary supply in slot 14.

Power Supplies
You can use one or two AC and/or DC power supplies in the chassis; each power supply uses one
slot. With one power supply, the chassis supports the CIM and up to 14 modules; with two
power supplies, the chassis supports the CIM and up to 13 modules. For specifications for the
power supplies, see Chapter 3.
An LED on each power supply lights green when the power is on. The chassis is a passive device
that does not generate an alarm if the power fails. However, the CIM includes circuitry and alarm
relay contacts that can route the alarm signal to an external device. The CIM forwards the power
status to the DMM, which logs the power failure and sends an alarm trap; for details, see the user
manuals for your CIM and DMM.
