AT-MCR12 Media Conversion Rack-Mount Chassis Installation Guide
Installing an AT-CV1000 Chassis in an AT-MCR12 Rack-Mount Chassis
In order to install the AT-CV1000 chassis in an AT-MCR12 rack-mount
chassis, an AT-CVMCR Installation Adapter, as shown in Figure 10, is
required.
Note
For detailed descriptions and installation procedures for the
AT-MCR12 rack-mount chassis, refer to the AT-MCR12 Media
Conversion Rack-Mount Chassis Installation Guide available on the
Allied Telesis website, www.alliedtelesis.com.
Calculating the
Power
Requirements
293
Figure 10. AT-CVMCR Installation Adapter
Even if your AT-MCR12 rack-mount chassis contains two AT-PWR4
power supply modules (a primary and an auxiliary), the total available
power for the modules in the chassis is limited to 80 Watts. This limitation
determines how many media converters the AT-MCR12 chassis can
support before the primary power supply shuts down.
To avoid power problems, Allied Telesis strongly recommends that you
calculate the total power required to supply your chosen media converters
before you install them in the AT-MCR12 chassis. Use the following
approximate power consumption guidelines for your calculation:
Use 6 Watts of power for any MC series media converter and the
AT-CV1000 with any of the Converteon line cards except the
AT-CM2K0S.
Use 9 Watts of power for the AT-CV1000 with an AT-CM2K0S line
card installed.
If the total power requirement exceeds the 80 Watt limit, then multiple
AT-MCR12 rack-mount chassis are required.
Installing the
AT-CV1000
Chassis
To install an AT-CV1000 chassis in an AT-MCR12 rack-mount chassis
using the AT-CVMCR Installation Adapter, perform the following
procedure:
35
Chapter 2: Installation

Wiring and Powering on a DC-Powered Chassis
To wire and power on a DC-powered chassis, perform the following
procedure:
Warning: As a safety precaution, install a circuit breaker with a
minimum value of 15 Amps between the equipment and the DC
power source.
Always connect the wires to the LAN equipment first before you
connect the wires to the circuit breaker. Do not work with HOT
feeds to avoid the danger of physical injury from electrical shock.
Always be sure that the circuit breaker is in the OFF position
before connecting the wires to the breaker.
Warning: Only trained and qualified personnel are allowed to
install or replace this equipment.
