Abstract
The present invention provides a kind of single UART port connector easy to plug, belongs to log read technical field, and the TXD/RXD signals of BMC two-way are switched to by two FSA3357 chips on Mini USB connectors respectively, this Mini USB connector is UART connector.Meet the definition of UART standards, meet UART specifications, be suitable on various server platforms, general rate is high.Reading system and BMC daily records can be realized by a UART interface, and without opening chassis lid, facilitate plug, reduce task difficulty, improve service efficiency and customer experience.
Description
Technical field
The present invention relates to log read technology more particularly to a kind of single UART port connectors easy to plug.
Background technology
With the fast development of server market, server product is gradually popularized in all trades and professions, for client
Group is also more and more diversified, and server can be potentially encountered some failures in the process of running（Such as power-off etc. suddenly）Or client
The daily record for needing to go grasping system according to other demands of oneself, to make client grasp the operation conditions of server in time, and
Reasonably operated.
On current server master board, mainly ensure the normal operation of system by two Fireware, one is
BIOS（Basic Input Output System, basic input output system）System is managed, another is BMC
（Baseboard Management Controller, baseboard management controller）Input/output interface is managed.
Current design scheme is：
In cabinet inside, there are two 4pinHeader（A kind of connector）It is connected respectively in the different UART ports of BMC chip, such as
Fruit is inserted on different Header to ensure to read system and BMC daily records respectively respectively using need to open chassis lid by jig.
If not only needing the hardware configuration of two Header it is found that the prior art reads daily record by foregoing description, and
And just have the condition of reading after needing opening chassis lid to find suitable position, so, the efficiency read will be influenced,
And reduce customer experience.
Invention content
In order to solve the above technical problems, the present invention proposes a kind of single UART port connector easy to plug.By this
Design, when use, need not open chassis lid, and a UART port can meet the needs of reading system and BMC daily records,
So that client is more prone to quickly read system log.
The technical scheme is that：
A kind of single UART port connector easy to plug, the TXD/RXD signals of BMC two-way are cut by two FSA3357 chips respectively
It changes on Mini USB connectors, this Mini USB connector is UART connector.
Wherein,
Two groups of TXD/RXD signals that BMC comes out, TXD1 and TXD2 are connected on Switch chips FSA3357, by RXD1 and
RXD2 is connected on another Switch chip FSA3357；
A GPIO signals, that is, Enable signal is pulled out from BMC, this Enable signal can go down to control it high in BMC administration interfaces
Low level carries out switch control to FSA3357, and signal all the way, respectively TXD_SW and RXD_SW are only exported from FSA3357, this two
It is a to be signally attached on general Mini USB connectors, and this connector is placed on case front panel.
When Enable signals are high, TXD1 is connected with TXD_SW, while RXD1 and RXD_SW conductings, such user will control
Tool, which is inserted on Mini USB connectors, just can be read system log.
If BMC daily records are read in user demand, need that Enable signals are set as low in BMC administration interfaces, at this point,
TXD2 and TXD_SW conductings, RXD2 and RXD_SW conductings, user, which is not necessarily to pull out jig, can read daily record inside BMC.
The beneficial effects of the invention are as follows
Only there are one physics UART ports, and system and BMC daily records can be read, and continuous read need not replace tap position.
The form that UART port is arranged to Mini USB is placed on case front panel, not only beautiful, it is often more important that Yong Huke
To realize that single UART connector reads system and BMC daily records, whole process is without opening chassis lid, and if continuous read does not need
Plug jig, better user experience.
Description of the drawings
Fig. 1 is the topological structure schematic diagram of the present invention；
Fig. 2 is single UART port connector realization principle figure.
Specific implementation mode
More detailed elaboration is carried out to present disclosure below：
A kind of single UART port easy to plug of the present invention, the TXD/RXD signals of BMC two-way pass through two FSA3357 chips respectively
It is switched on Mini USB connectors, this Mini USB connector is UART connector, as shown in Figure 1.
Operation principle as shown in Fig. 2,
1）The TXD1 and RXD1 exported from BMC is the UART signal for reading system log, and TXD2 and RXD2 are to read BMC daily records
UART signal.U1 and U2 in Fig. 2 are FSA3357 chips, can control tri- channels B0/B1/B2 by S1 and S2 signals
Switch, the present invention only need to remove control B1/B2 signals by S1, and A is output signal.
2）When needing to read system log, it is arranged without additional since the ends S1, that is, FM_UARTSW_LSB_N is defaulted as height,
FSA3357 chips B1 is connected with A at this time, i.e. U1 chips BMC_TXD1=MUX_PORT_UART_TX, and U2 chips BMC_RXD1=
MUX_PORT_UART_RX, at this point, what is read on standard Mini USB connectors J1 is the UART signal of system log, user is
The daily record of printable whole system.
3）When user needs to read BMC daily records, FM_UARTSW_LSB_N signals can be set in BMC administration interfaces it is low,
FSA3367 chips B2 is connected with A at this time.I.e.：U1 chips BMC_TXD2=MUX_PORT_UART_TX, U2 chip BMC_RXD2=
MUX_PORT_UART_RX, what is be connected on standard Mini USB connectors J1 at this time is the UART signal of BMC_TXD2/RXD2, i.e.,
BMC daily records can be read.
4）Mini USB connectors J1 is standard Mini USB interfaces, is placed on case front panel, user need not open machine
Case lid directly plugs jig use.
Single UART port scheme easy to plug proposed by the present invention is achieved as a result,.
