Shelf Management Commands
cnfndparms
An AC power supply tray holds six power supply units (PSUs). (Refer to the Cisco MGX 8850 Hardware
Installation Guide for details.) A supply belongs to one of two groups: A1–A3 or B1–B3. An 8-bit
hexadecimal number identifies an individual supply. The value for Option 6 can be the sum of any
combination of hexadecimal numbers. For example, the value for requiring A1 and B1 is:
0x01 + 0x10 = 0x11
Required Fan Trays
Option 7 lets you specify required fan trays for the purpose of alarm generation. You can specify either
or both fan trays as required. The value is an 8-bit hexadecimal number.
Note
The switch requires two fan trays for cooling purposes regardless of the number you specify for alarm
purposes with cnfndparms.
•
0x0 means no fan try requirement. (The enclosure still must have at least one fan tray for cooling.
•
0x01 refers to the bottom fan tray.
•
0x02 refers to the top fan tray.
To require top and bottom fan trays, for example, enter a hexadecimal 3 for the option value:
0x01+0x02=0x03
Option Values
This scheme allows substantial flexibility for the numeric value of current and future options. This
command supports various number formats as a part of its flexibility, as follows:
•
An 8-bit decimal has the range 0–255.
•
A 16-bit decimal number has the range 0–65535.
•
A 32-bit decimal number has the range 0–4294962795.
•
An 8-bit hexadecimal number has the range 0–0xff.
•
A 16-bit hexadecimal number has the range 0–0xffff
•
A 32-bit hexadecimal number has the range 0–0xffffffff.
Each option description states the type of number involved and the actual range for that option.
Alternatively, the description states if the choice is “yes” to enable of “no” to disable.
