Description
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.
Mounting brackets: Support installation in a standard 19-inch rack or telecommunications cabinet.
Flush and mid-mount options are supported. In addition, each bracket contains an electrostatic
discharge jack for use when handling equipment.
Upper fan tray: Draws air through the chassis for cooling and ventilation. It then exhausts warmed
air through the vents at the upper-rear of the chassis.
Upper bezel: Covers the upper fan tray bay.
Lower fan 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 ambient 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.
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.
