This chapter briefly describes the steps and tools that are required for the physical installation of the chassis.
|
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.
|
|
|
Mounting brackets: 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.
|
|
|
Lower fan tray cover: Secures the lower fan tray assembly. 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 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.
There are two versions of the PFU. The versions are differentiated by the current rating of the circuit breakers: 125 amp and 165 amp.
125A and 165A PFUs are not interchangeable. Both PFUs installed in chassis must be of the same type.
Verify that the PFUs are correct for the chassis. The chassis part number label located in the rear center of the chassis just above the PFU slots identifies the proper PFUs to be used. |
IMPORTANT: Unpacking instructions are not provided in this document. Please refer to document that was shipped with the chassis, 902-00-0003, Unpacking the Chassis, for information and instructions on this topic.Once the installation has been validated, you will be directed to the Administration and Configuration Reference that provides instructions on how to configure the system for operation.
The following hand tools are required for installation of the chassis, application and line cards, fan tray assemblies, and power filter units:
|
l
|
Phillips screwdriver #2 and #1. Used to tighten thumb-screws on cards, fan tray assemblies, PFUs, and mounting brackets.
|
|
l
|
7/16- or 9/16-inch nut driver or ratchet and socket set. Used to connect power and return cables. The 165A PFU requires the 9/16-inch; the 125A PFU requires the 7/16-inch.
|
|
l
|
Grounding wrist and/or heel straps. Used to prevent Electro-Static Discharge (ESD) as discussed in the Protecting Against Electro-static Discharge section that follows.
|
ESD During installation, maintenance, and/or removal, wear grounding wrist and/or heel straps to avoid ESD damage to the components. Failure to do so could result in damage to electrical components and could potentially void your warranty.The following equipment is necessary to install the chassis and verify that it is ready for configuration:
|
l
|
IMPORTANT: Additional hardware, such as extension brackets, may be used to install the chassis in a standard 23-inch (58.42 cm) cabinet or rack.|
l
|
A computer or terminal server with a 9-pin RS-232C serial port, or 25-to-9-pin male RS-232C adapter. Used to connect to the SPIO's Console Port for accessing the Command Line Interface (CLI) for system configuration.
|
Electro-Static Discharge (ESD) can cause serious damage to 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.
IMPORTANT: Before the ESD you use the jacks on the chassis and its mounting brackets to provide ESD protection, you must first connect the chassis to ground according to the instructions in the “Chassis Installation”chapter of this document.
