Tsis tas li ntawd, lub chassis tuaj yeem pab tiv thaiv cov khoom siv sib txuas lus rhiab los ntawm kev puas tsuaj rau lub cev thiab ib puag ncig.

## 3. Dab tsi yog qhov txiaj ntsig ntawm kev siv USB 3.0 hauv 2U khib?

Kev koom ua ke USB 3.0 rau hauv 2U khib rooj plaub muaj ntau qhov zoo. Ua ntej, nws muab cov ntaub ntawv hloov pauv ceev ceev, uas yog qhov tseem ceeb rau kev txav cov ntaub ntawv loj lossis thaub qab sai. Qhov no tshwj xeeb tshaj yog muaj txiaj ntsig zoo rau kev siv kev ruaj ntseg network uas yuav tsum tau nkag mus rau cov ntaub ntawv raws sijhawm. Tsis tas li ntawd, USB 3.0 cov chaw nres nkoj tuaj yeem yooj yim txuas cov khoom siv sab nraud xws li chaw cia khoom lossis lub koob yees duab kev nyab xeeb, txhim kho tag nrho cov haujlwm ntawm kev teeb tsa khib. Backward compatibility nrog USB 2.0 kuj ua kom ntseeg tau tias cov khoom qub tseem yuav ua haujlwm zoo.

## 4. Cov ntaub ntawv 2U khib puas tuaj yeem siv rau kev siv optoelectronic?

Yog lawm, 2U racks tuaj yeem siv tau zoo rau kev siv optoelectronic. Cov thawv no tuaj yeem nyob hauv ntau yam khoom siv optoelectronic xws li lasers, photodetectors, thiab optical transceivers uas tseem ceeb rau kev sib txuas lus thiab cov ntaub ntawv xa mus. Kev tswj hwm ib puag ncig ntawm lub thawv khib nyiab pab tiv thaiv cov khoom siv optoelectronic rhiab heev los ntawm plua plav, ya raws, thiab kev puas tsuaj rau lub cev, ua kom pom kev ua haujlwm zoo thiab ua haujlwm ntev. Tsis tas li ntawd, cov qauv tsim qauv tso cai rau kev hloov kho kom yooj yim thiab hloov kho raws li thev naus laus zis hloov zuj zus.

## 5. Kuv yuav tsum xav txog dab tsi thaum xaiv 2U khib rau kuv lub network kev ruaj ntseg teeb?

Thaum xaiv 2U khib rau koj lub network kev ruaj ntseg teeb, xav txog cov hauv qab no:

- **Qhov cua txias thiab qhov cua**: Xyuas kom muaj cua txaus rau lub chassis tiv thaiv lub cuab yeej los ntawm overheating.
- ** Khoom siv thiab tsim kom zoo**: Saib rau kev tsim kho kom ruaj khov uas tuaj yeem nqa qhov hnyav ntawm lub cuab yeej thiab muab kev tiv thaiv kev puas tsuaj rau lub cev.
- **Cable Management**: Xaiv tus qauv tsim uas tso cai rau kev teeb tsa cable routing kom txo qis clutter thiab txhim kho kev nkag tau yooj yim.
- **Accessibility**: Xaiv ib lub thawv uas yooj yim nkag mus rau pem hauv ntej thiab nram qab panels ntawm lub cuab yeej rau kev tu thiab kho teeb meem.
- **Expansion Options**: Xav txog cov kev xav tau yav tom ntej thiab xaiv lub chassis uas tuaj yeem ua raws li cov khoom siv ntxiv lossis hloov kho dua tshiab.

Ua tib zoo xav txog cov xwm txheej no, koj tuaj yeem xaiv 2U rackmount rooj plaub kom ua tau raws li koj lub network kev ruaj ntseg thiab kev xav tau cia.
