# 2.3 Shelf SEEPROM

The Shelf SEEPROM is a repository of the shelf-specific information, capabilities of the system and other user configurable options.

The SEEPROM contains as example:

• a list of which slots are connected together
• how the update channels are routed
how many slots are in the system
what the maximum power is to each slot
the serial number of the Shelf
the backplane topology etc.

The Shelf Managers use this information to provide functions such as electronic keying, controlling the power state of the system, etc.

The Shelf Managers cache the information that is stored in the SEEPROMs so that the SEEPROM is only needed when the Shelf Managers are first inserted or when the Shelf is first turned on.

The redundant SEEPROMs ensure that if one is corrupt or non-functional, the second can provide the necessary information. The Shelf Manager selects what set of information is correct and then synchronizes the two SEEPROMs from the internally cached copy of the SEEPROM information.

# 2.3.1 Shelf SEEPROM Location

The SEEPROMs are located at the rear side of the backplane.

# 2.3.2 Shelf SEEPROMs I²C Addresses

![The image displays a solid blue rectangle containing a centered, white lowercase letter 'i'. This is the standard icon used to represent 'information.'](.atca-81414pd-50-1g049-1000-10/f2ef39d5f0b22c82e7df738d1d9a0d8a258118eb779d908a6705b783fc3e5340.jpg)

Required wire size: #3 AWG or #2 AWG, maximum length 3 m.

Required terminals: Use only two hole lug terminals. (For example PANDUIT LCC2-14AHQ or LCD2-14AHQ with 45° angle)

# 5 Fan Tray

# 5.1 Introduction

The Fan Tray is an intelligent FRU controlled by the ShMCs via IPMB.

The interchangeable Fan Tray is equipped with 8 high speed / high air flow fans controlled as a group by the IPM Controller in the Fan Tray.

The Fan Tray is locked into the Shelf with captive screws. A Hot Swap push button is used to provide hot-swap functionality.

The Fan Tray provides:

• A blue Hot Swap LED
• A red Fan Tray Fault LED
• A green Fan Tray OK LED
• A Hot Swap push button

The Fan Tray is controlled via an on-board IPM controller. The Shelf Manager performs management of the Fan Tray through the two independent bussed IPMB connections.

With optional on-blade shelf management, the circuit breaker status signals of the PEM and the SEEPROM on the backplane are connected to the internal I²C bus on the Fan Trays. The on-blade Shelf Manager has access to these components via the IPM controller of the Fan Trays.

The speed of each individual fan is monitored. If any of the fan speeds drops below the desired fan speed, a System Event Log (SEL) entry is logged by the Shelf Manager. The Shelf Manager then generates alerts and sets alarm conditions as necessary.

The system is designed to run indefinitely with any single fan failure. When one fan fails, all other fans are set to full speed.

# 5.3 Fan Tray Connectors and Indicators

The front panel includes a green Fan Tray OK LED, a red Fan Tray Fault LED, and a blue Hot Swap LED.

The Hot Swap push button indicates to the Shelf Managers that the Fan Tray is about to be removed. Its use is optional, but it is provided so that service personnel can be trained to look for a blue LED to be illuminated on any active component before removing it from the system. Once the operator pushes the Hot Swap button, the Shelf Manager is informed of the pending extraction. When the Shelf Manager feels it is “safe“ to remove the Fan Tray, the blue Hot Swap LED illuminates solid.

# Hazardous voltage!

Before working ensure that the power is removed from the power connection cables.

The shelf supports low-power and high-power DC-Power Entry Modules (PEMs) with or without redundant inputs.

The pluggable DC Power Entry Module (PEM) is located at the rear bottom side of the Shelf. The PEM provides power terminals for 100 A power feeds. Each power feed consists of $\mathsf { a } - 4 8 \mathsf { V } _ { \mathsf { D C } }$ cable and its corresponding RTN cable.

The power filtering consists of filtered power terminals and a discrete line-filter for each power branch. The input voltage range for the Shelf is from $- 4 0 \vee _ { \mathsf { D C } } \mathsf { t o } - 7 5 \bigvee _ { \mathsf { D C } }$ .

Overcurrent protection is provided by 100 A circuit breakers in the -48 VDC input lines. Power distribution within the PEM is divided into 4 power branches.

![A blue square icon containing a white lowercase letter 'i' in the center.](.atca-81414pd-50-1g049-1000-10/e212a10d18e39acf82d8ca224d5220f141b1f6c221fb43483a6159e1438e271a.jpg)

The System can be powered using a regular telecommunication power supply of -48/-60 $V _ { D C }$ with a $V _ { D C }$ return. The specified voltage range is from -40 $V _ { D C }$ to-75 $V _ { D C } .$ . The Shelf supports redundant power inputs but the two inputs should be independently powered.
