Sub-component Identification Key
Chassis: Supports 16
front-loading slots for application cards and 32 rear-loading slots for line
cards. The chassis ships with blanking panels over every slot except the
following: 1, 8, 17, and 24. These are intentionally left uncovered for the
initial installation of system components.
Supports installation in a standard 19-inch rack or telecommunications cabinet.
Standard and mid-mount options are supported. In addition, each bracket
contains an electro-static discharge jack for use when handling equipment.
Upper fan tray: Draws air
up through the chassis for cooling and ventilation and exhausts the air through
the vents at the upper-rear of the chassis.
Upper bezel: Covers the
upper fan tray bay.
tray cover/EMI shield: Secures the lower fan tray assembly in place and
serves as an EMI shield. The cover also provides an air baffle allowing air to
enter into the chassis.
Lower bezel: Covers the
lower fan tray bay.
Lower fan tray assembly:
Draws air into the chassis through the chassis' front and sides for cooling and
ventilation. It is equipped with a particulate air filter to prevent dust and
debris from entering the system.
Power Filter Units
(PFUs): Each of the system's two 165 amp PFUs provides -48 VDC power to the
chassis and its associated cards. Each load-sharing PFU operates independently
from the other to ensure maximum power feed redundancy.

summarizes power, grounding, environment, and clearance requirements
that must be met prior to installing and operating the ASR 5000.
For detailed information, refer to the Technical Specifications chapter.
Each PFU requires
a power feed of 160A @ -48VDC (nominal). The feeds should
be routed to the installation rack from the site power supply using
adequately sized conductors and circuit breakers in accordance with
local electrical codes.
The chassis must be
grounded to a site ground point using the recommended conductors
and lugs. The ground point should be in close proximity to the ASR 5000
chassis to assure adequate conductivity.
heating ventilation and air conditioning (HVAC) systems must be
sized to maintain the operating temperatures and relative humidity
specified in the Technical
Specifications chapter. HVAC capacity requirements will vary
based on the system configuration and associated power draw, as
well as the operational characteristics of other equipment installed
at the site.
must be maintained at the front and rear of the ASR 5000
chassis to assure proper air flow and allow maintenance access for
the installation, removal and replacement of components. The recommended
clearance is 30 to 36 inches (76 to 92 centimeters) at the front
and rear of the chassis.
Discharge (ESD) can cause serious damage to sensitive components on the
chassis, its sub-components, and/or the cards installed in the chassis. To
prevent damage from ESD, you must take proper grounding precautions before
handling the chassis or any of its components.
To aid in the
prevention of ESD damage, the chassis and its mounting brackets are equipped
with ESD jacks. Use the jacks in conjunction with grounding wrist straps when
handling the chassis and/or its components. The following figure shows the
location of the jacks.
Before using the
ESD jacks on the chassis and its mounting brackets to provide protection, you
must first connect the chassis to earth ground as described in the
Installation chapter of this document.
