2. تعليمات الإعداد
2.1. محتويات العبوة
تأكد من أن الحزمة الخاصة بك تحتوي على العناصر التالية:
- Cisco SG500-28MPP-K9 28-Port Gigabit Max PoE+ Managed Switch
- سلك الطاقة
- مجموعة التثبيت على الرف
- كابل وحدة التحكم (RJ-45 إلى DB-9)
- Documentation CD (or link to online resources)
2.2. التثبيت المادي
يمكن تركيب المحول على سطح المكتب أو تثبيته في رف معدات قياسي مقاس 19 بوصة.
- تثبيت سطح المكتب: ضع المفتاح على سطح مستوٍ وثابت. تأكد من وجود تهوية كافية حول الجهاز.
- التثبيت على الرف: ثبّت حوامل التثبيت المرفقة على جانبي المفتاح باستخدام البراغي المرفقة. ثبّت المفتاح في رفّ الجهاز.
2.3. توصيل المفتاح
Follow these steps to connect your switch:
- Connect the power cord to the switch's power inlet and then to a grounded electrical outlet.
- Connect your network devices (computers, IP phones, wireless access points) to the switch's Gigabit Ethernet ports using standard Ethernet cables. The switch supports Power over Ethernet Plus (PoE+) on its ports.
- For initial configuration, connect a computer to the switch's console port using the provided console cable, or connect a computer to any Ethernet port and configure its IP address to be in the same subnet as the switch's default IP address (typically 192.168.1.254).

3. تشغيل المفتاح
3.1. التشغيل الأولي
Once connected to power, the switch will automatically power on. Observe the system LED indicators. The 'System' LED should turn green, indicating normal operation. Port LEDs will illuminate when a device is connected and active.
3.2. التكوين الأساسي
The Cisco SG500-28MPP-K9 is a managed switch, offering extensive configuration options via a web- واجهة المستخدم الرسومية (GUI) أو واجهة سطر الأوامر (CLI).
- Web الوصول إلى واجهة المستخدم الرسومية: افتح web browser and enter the switch's default IP address (e.g., http://192.168.1.254). Log in using the default credentials (refer to the documentation for specific defaults, often 'cisco' for both username and password).
- الوصول إلى واجهة سطر الأوامر: Use a terminal emulation program (e.g., PuTTY) to connect via the console port. Configure the serial connection settings (e.g., 115200 baud, 8 data bits, no parity, 1 stop bit, no flow control).
It is highly recommended to change default passwords immediately after initial access for security purposes.
3.3. الميزات الرئيسيةview

5. استكشاف الأخطاء وإصلاحها
5.1. المشكلات الشائعة والحلول
- لا يوجد طاقة:
علامة مرض: مؤشر LED للطاقة مطفأ.
حل: Check the power cord connection to the switch and the electrical outlet. Ensure the outlet is functional. - لا يوجد اتصال بالشبكة:
علامة مرض: Devices connected to the switch cannot access the network.
حل: Verify that Ethernet cables are securely connected to both the switch and the devices. Check port status LEDs; a solid green or blinking green indicates a link. Ensure the switch has a valid IP configuration and is connected to your router/gateway. - جهاز PoE لا يعمل:
علامة مرض: PoE-powered device (e.g., IP phone) does not receive power.
حل: Ensure the device is PoE-compatible. Check the switch's PoE status LEDs for the specific port. Verify PoE settings in the switch's management interface. Ensure the total PoE budget of the switch is not exceeded. - لا يمكن الوصول Web واجهة المستخدم الرسومية:
علامة مرض: Browser cannot reach the switch's IP address.
حل: Verify your computer's IP address is in the same subnet as the switch. Ping the switch's IP address to confirm network reachability. Clear browser cache or try a different browser.
