Table 1. Chassis and Sub-component Identification Key
Item Description
1 Chassis: Supports 16 front-loading slots for application cards and 32 rear-loading slots for line cards. To support the
XGLC, a full-height line card, remove the half-height guide from the rear slots.
The chassis ships with blanking panels over every slot except the following: 1, 8, 17, and 24. These are intentionally left
uncovered for initial installation of application and line cards.
Refer to the ASR 5000 Chassis Descriptions section for additional information.
2 Mounting brackets: Support 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.
Refer to the Mounting Options section for additional information.
3 Upper fan tray: Draws air up through the chassis for cooling and ventilation. It then exhausts air through the vents at the
upper-rear of the chassis.
Refer to the Fan Tray Assemblies section for additional information.
4 Upper bezel: Covers the upper fan tray bay.
5 Lower fan tray cover: Secures the lower fan tray assembly in place. The cover also provides an air baffle allowing air to
enter into the chassis.
6 Lower bezel: Covers the lower fan tray bay.
7 Lower fan tray assembly: Draws air 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.
Refer to the Fan Tray Assemblies section for additional information.
8 Power Filter Units (PFUs): Each of the system's two PFUs provides -48 VDC power to the chassis and its associated
cards. Each load-sharing PFU operates independently of the other to ensure maximum power feed redundancy.
Refer to the Power Filter Units section for more information.
