Always to master control board card, level-one frame control board of the master control board card again into the rack for sending alarm data is sent out by RJ-45 twisted-pair feeders
The order for sending out alarm is sent, signal alarm bell in the same rack can be triggered by receiving the level-one frame control board of alert command.
Embodiment 7：
It is shown in Figure 2, on the basis of embodiment 1, the work of alert communication equipment can be complained in multiple distribution open frames
It is as follows to make flow：
S1. primary expansion subrack of any one expansion subrack as the rack is selected in each rack, and one is equipped in frame
Grade frame control board；For other expansion subrack in rack as common expansion subrack, frame is interior to be equipped with two level frame control board.Main control frame can be with
It is considered as a kind of special primary expansion subrack, master control board card can also be considered as a kind of special level-one frame control board.
S2. configuration association, primary expansion subrack are carried out to board and the expansion subrack in each rack on a workstation and other is general
Logical expansion subrack carries out configuration association.
S3. the configuration association relationship configured in S2 is handed down to by master control board card by work station so that master control board card can
Know which expansion subrack any one piece of board belongs to, point rack warning light is implemented by the main frame control board on which primary expansion subrack
It is operated with signal alarm bell is rung.
Level-one frame control board is inserted in primary expansion subrack, and two level frame control board is inserted in common expansion subrack；Primary expansion subrack
It is connected by RJ-45 twisted-pair feeders with common expansion subrack with common expansion subrack, common expansion subrack, RJ-45 twisted-pair feeders serve as each extension
The channel that alarm data interacts between frame.
S4. when equipment works after master control board card receives the alarm of other failure boards, board place is calculated successively
Expansion subrack, the associated primary expansion subrack of the expansion subrack and the level-one frame control board on the primary expansion subrack address.If
Master control board card is stuck in the same expansion subrack with faulty board, then alarm data is reported to by faulty board card by backboard industry ethernet
Master control board card；If master control board card and failure board, not in same sub- frame, faulty board card is by between frame on RJ-45 twisted-pair feeders
Offer master control board card.
S5. master control board card sends alert command to calculated correct in S4 by the RJ-45 twisted-pair feeders between expansion subrack
Level-one frame control board on primary expansion subrack, allows the frame of rack where its level-one frame control board (i.e. failure board place rack)
Warning light is pushed up, while driving the frame top alarm thumper of level-one frame control board place rack (i.e. rack where failure board) to ring and accusing
Alarm bell；Rather than put master control board card where rack or other top warning lights, nor driving master control board card where rack or
The frame top alarm thumper of other racks rings signal alarm bell.
S6. level-one frame control board lights the frame top warning light of its place rack after receiving alert command, driving alarm is thundered
Device rings signal alarm bell.
The present embodiment realizes the board event that equipment operation maintenance personnel can not only be known by alarm modulating signal in main control frame
Barrier, moreover it is possible to board faults be excluded by signal alarm bell signal in time, to reduce remover apparatus fault time, improve equipment O&M effect
Rate.Overcome according in traditional frame top warning light lighting scheme when with master control board card not the board of same rack in the event of failure
What equipment was lighted is not the frame top warning light of rack where the frame top warning light but master control board card of rack where failure board, this
Sample can not allow equipment operation maintenance personnel rapidly comform the board known in multi-frame in which rack it is faulty and carry out in time therefore
Barrier excludes.
The utility model is not limited to the above embodiment, for those skilled in the art, not
Under the premise of being detached from the utility model principle, several improvements and modifications can also be made, these improvements and modifications are also considered as this reality
Within novel protection domain.The content not being described in detail in this specification belongs to well known to professional and technical personnel in the field
The prior art.
