3. התקנה

Follow these steps to safely install the network module into a compatible Cisco Catalyst 9300 series switch.

אמצעי בטיחות:

• Ensure the switch is powered off and disconnected from the power source before installation.
• ענדו רצועת פרק כף יד למניעת פריקה אלקטרוסטטית (ESD) המחוברת למשטח מוארק כדי למנוע פריקה אלקטרוסטטית.
• Handle the module by its edges; avoid touching components or connectors.

שלבי התקנה:

1. הכן את ההחלפה: Power off the Cisco Catalyst 9300 series switch and disconnect all power cables.
2. אתר את חריץ המודול: Identify an available network module slot on the rear panel of the switch. If a blank cover is present, remove it by unscrewing the captive screws and pulling the cover out.
3. הכנס את המודול: Align the network module with the empty slot. Gently slide the module into the slot until it is fully seated. Ensure the module's connectors engage properly with the switch's backplane.
4. אבטח את המודול: Tighten the captive screws on the module's faceplate to secure it firmly in place.
5. חבר מחדש את החשמל: חבר מחדש את כבלי החשמל למתג והפעל אותו.
6. ודא התקנה: After the switch boots up, verify that the module is detected and operational through the switch's command-line interface (CLI) or management interface.

4. הוראות הפעלה

Once the network module is installed, you can begin configuring and using its 25 Gigabit Ethernet ports.

Connecting SFP28 Transceivers:

1. Select Transceivers: Use only Cisco-qualified 25G SFP28 transceivers compatible with the Catalyst 9300 series.
2. Insert Transceiver: Gently insert the SFP28 transceiver into one of the module's 25G slots until it clicks into place.
3. חיבור כבל סיב אופטי: Connect the appropriate fiber optic cable to the SFP28 transceiver. Ensure the cable type matches the transceiver specifications (e.g., multimode or single-mode).
4. Verify Link Status: Check the port status LEDs on the module or use the switch's CLI to confirm that the link is up and operational.

Basic Configuration (CLI Example):

For detailed configuration, refer to the Cisco Catalyst 9300 Series Switch Software Configuration Guide. Below is a basic example for interface configuration:

Switch# configure terminalSwitch(config)# interface TwentyFiveGigabitEthernet X/Y/Z   (Replace X/Y/Z with actual interface ID)Switch(config-if)# description Uplink_to_CoreSwitch(config-if)# no shutdownSwitch(config-if)# speed 25000Switch(config-if)# duplex fullSwitch(config-if)# endSwitch# write memory

פֶּתֶק: The interface numbering (X/Y/Z) depends on the specific switch model and slot where the module is installed. Consult your switch documentation for exact interface identification.

5. תחזוקה
