When you physically remove an expansion card (blade) from an NEC SL phone system, it’s best practice to delete that blade from system programming as well. This prevents potential programming issues down the road.
For example, if a customer replaces their CO lines with a T1/PRI and no longer needs the CO-Line card, removing the blade physically and virtually keeps the database clean.
This Tech Tip applies to both the NEC SL2100 and NEC SL1100 phone systems.
Step 1: Back Up the Phone System
Before removing or deleting a blade, perform a database backup to ensure a restorable copy of system settings is saved.
- Connect to the phone system using PCPro
How to Connect to the NEC SL2100 or SL1100 Phone System for Programming - Click the Download button
(The large, blue downward arrow in the Home tab) - When the download is complete, click the File tab
- Choose Save As
- Enter a file name for the backup
- Click Save to store the file on your computer
Step 2: Physically Remove the Blade
- Power down the phone system using the power switch
- Wait until all CPU LEDs are off
- Disconnect the phone system from its power source
- Use appropriate tools to remove the blade from the SL chassis
- Power the phone system back on
Step 3: Virtually Remove the Blade
- Connect to the phone system using WEBPro
(See: How to Connect to the NEC SL2100 or SL1100 Phone System for Programming) - Click the Blade Configuration icon at the top of the page
- Check the box next to the blade you want to remove
- Click the Delete Blades button
- Log out of WEBPro
- Power down the phone system
- Wait until all CPU LEDs are off
- Power the phone system back on
Step 4: Verify the Changes
- Reconnect to the phone system using WEBPro
- Confirm the blade is no longer recognized in the Blade Configuration menu
Installing a New Blade (Optional)
If installing a replacement blade:
- Power down the phone system
- Install the new blade into the chassis
- Power the system back on
The system will recognize the new blade during startup.
