Chapter 9: MIB Path Summary and Trap Definitions
A/B Switch System SNMP Variable Definitions:
[ab Sys te mG an gP or t ] —1.3 .6 .1.4 .1.9 47 7.1.4 .1
A/B Switch System gang port. This variable is used to control all A/B s witch ports in the system. A system may consist of up to
255 racks, each rack containing up to 16 A/B switch por ts. On a “GET” of this variable, only rack with address 0x01 will respond.
If any of the A/B s witch ports in rack 0x01 are at position A, the “system” status will be A. If all of the A /B switch ports in rack
0x01 are at position B, the “system” status will be B. If there are no A/B switch port s installed in rack 0x01, the “system” status
will be empty.
[abR ackTa bl e] —1. 3.6 .1.4.1.9 477.1.4 .2
A/B Switch Rack variable table. This variable is not directly accessible.
[abRackIndex]—1.3.6.1.4.1.9477.1.4.2.1.1.RackIndex
Switch “Rack” address. The “Rack” address is set via an eight-position dip switch. Each rack in the system MUST have a unique
address, in the range of 0x01 to 0xFF hex. Address 0x00 is invalid, and must not be used. This is a read-only variable.
[abRackGangPort]—1.3.6.1.4.1.9477.1.4.2.1.2.RackIndex
A/B Switch Rack gang port. This variable is used to control all A/B switch ports in a rack. A rack may contain up to 16 A/B switch
ports. On a “GET” of this variable, the addressed rack will respond as follows. If any of the A/ B switch ports in the addressed rack
are at position A, the “rack” status will be A. If all of the A/B switch por ts in the addressed rack are at position B, the “rack”
status will be B. If there are no A /B switch ports installed in the addressed rack, the “rack” status will be empty.
[abRackKeyStat]—1.3.6.1.4.1.9477.1.4.2.1.3.RackIndex
A/B Switch Rack Key-Lock Switch Status. This is a read-only variable. This variable can be used to determine if the Key-Lock Switch
is in the OFF or ON position. The front panel switches in the rack are disabled when the Key-Lock Switch is in the OFF position.
The A/B Switches will still respond to switch control signals and commands from the GANG-IN and GANG-OUT ports.
[abRackPowerStat]—1.3.6.1.4.1.9477.1.4.2.1.4.RackIndex
A/B Switch Rack Power Status. This is a read-only variable. On the switch, there are two DC power entry connectors. If power is
applied to both power entry connectors, the Power Status will repor t “TwoSupplies”. If power is applied to only one of the power
entry connectors, the Power Status will report “One Supply Down.”
[abRackSoftwareVersion]—1.3.6.1.4.1.9477.1.4.2.1.5.RackIndex
Microcontroller Software Version. This is a read-only variable, and is limited to a maximum of 14 characters.
[abRackName]—1.3.6.1.4.1.9477.1.4.2.1.6.RackIndex
Rack Identification String. The string is limited to a maximum of 13 characters. Although this MI B variable may be up to 14
characters long, the switch limits this variable to 13 characters.
[abR ack Car ds] — 1.3. 6.1.4 .1.947 7.1.4.2 .1.7.Rac kI nde x
A/B Switch Rack Status / Control. One character for each of the sixteen ports in the rack. Port s that are not populated will be
represented by an X character. Characters represent Ports 1 through 16, from left to right. This variable may b e used to set any or
all ports in a rack with a single command. When setting, enter one character for each port in the rack, up to 16 characters. Valid
characters are A, B, or X to leave a por t unchanged. When set with a single character, this command functions the same as a set
abSwitchPort command. When set with more than one character, this command overrides any group settings in place (see
abRackGroups for more information on group settings).
NOTE: RJ-45 models that switch all 8 leads are able to do so by using a different version of switch firmware that makes use of the
switch relays normally associated with ports 9 thru 16. These models force the port 9 connection state to match port 1,
port 10 to match port 2, etc. The abRackCards object cannot be used to override this pre-defined grouping of ports 1 & 9,
2 & 10, 3 & 11, etc. on these models of the switch.
