Description
This document describes how to verify the incoming power and power distribution 

within the Netra[TM] CT 900
Symptoms


  • Shelf dead
    
	
  • Chassis dead
    
	
  • Blade dead
    
	
  • Can't power up Blade
    




Purpose/Scope

The Netra CT 900
chassis has eight power input feeds split across two redundant Power
Entry Modules. Within the Shelf (chassis), these supplies are spread
across four zones. This document describes the procedures to check
that the power is present and correct at the input to the Sun Netra
CT 900 and that the power distribution within the shelf is correctly
configured to supply the power required for the boards that are
installed. 



Steps to Follow
These are the steps to follow



	
	
	
	
	
	
	
	
	



    
	
  • Verify the state of the LEDs on each of the boards
    



The LEDs on each board will
help to identify whether the problem is localized to a single board
or affects a group of components or even the entire shelf.


See <Document: 1019516.1>




    
	
  • Verify the
	shelf has incoming power
    



The Netra CT900 has two
redundant power entry modules known as PEMs located at the rear of
the shelf. These PEMs take -48V DC power inputs and distribute power
to the rest of the system. Each of the feeds should be individually
protected via circuit breakers. The loss of an individual feed or a
complete PEM should not cause the shelf to go down.


If the shelf appears
completely dead, i.e. no LEDS illuminated, or no sound of fans
turning, verify external power is available and that the circuit
breakers are in the on position. Any problems in this area may
require the assistance of the site electrician.


    
	
  • Verify
	available shelf power
    




Early model chassis referred
to the Power Entry Modules as PEM-A and PEM-B.


Later models refer to them
as PEM-1 and PEM-2. The following table indicates the origin of each
feed (numbered 0 through 7) and the zones they support (numbered 1
through 4).

If zone 2 and or zone 3 power is available, then one
or both the shelf managers (ShMM) will power up and allow access to
the system for further checks.


Log into the active shelf manager using either the
serial management port connection via the alarm card (refer to
document <Document: 1019404.1> or through the network (assumes
network connected and active). Refer to documents <Document: 1017986.1> and <Document: 1005533.1> verifying external network


    
	
  • Confirm you are on the active ShMM
    



# clia shmstatus


Pigeon Point Shelf
Manager Command Line Interpreter


Host: "Active"


#


    
	
  • Verify the incoming power feeds are present
	using the clia shelf power distribution command
    



Check the value for the parameter "Maximum
External Available Current" for feed 00 through to feed 07 is
showing 28 amps. If power is missing from an individual feed it will
show 0 amps.


This output also shows the FRU address for each of
the boards on a particular feed. The "FRU Addr" given in
this output is the Hardware Address of the board. To convert to a
physical board refer to document <Document: 1019506.1>

  • Check the power requirement matches
	the power allowance for each slot using the clia shelf -v
	power_management command
    



The amount of power allowed by the Shelf manager for
the slot is shown by the parameter "Maximum FRU Power
Capabilities". Note: These values differ depending on the
Chassis/ShMM firmware level.


The amount of power requested by the board and
subsequently allocated is shown by the parameter "Currently
Assigned Power"


If the board requests more power than is allowed for
the slot, the board will not power up
