عیب یابی
این بخش مراحل عیبیابی اولیه برای مشکلات رایج را ارائه میدهد.
مسائل و راه حل های رایج:
- بدون برق:
- مطمئن شوید که سیم برق به طور ایمن به سوئیچ و پریز برق وصل شده است.
- از عملکرد پریز برق اطمینان حاصل کنید.
- بدون اتصال به شبکه:
- Check the link/activity LEDs on the switch ports. A solid green or blinking green LED indicates a valid link and activity.
- Ensure Ethernet cables are properly connected and not damaged.
- تأیید کنید که دستگاه متصل روشن است و به درستی کار میکند.
- دستگاه PoE روشن نمیشود:
- Confirm the device is PoE-compatible.
- Check the PoE status via the switch's web GUI to ensure power is being delivered and the total PoE budget is not exceeded.
- سعی کنید دستگاه را به یک پورت PoE دیگر وصل کنید.
- دسترسی امکان پذیر نیست Web رابط کاربری گرافیکی:
- مطمئن شوید که کامپیوتر شما در همان بخش شبکهای است که سوئیچ به آن متصل است.
- Verify the switch's IP address. If unknown, use the Cisco FindIT Network Manager or reset the switch to factory defaults (refer to the Reset button on the front panel).
- کش مرورگرتون رو پاک کنید یا با یه مرورگر دیگه امتحان کنید.
