Accelero Server (On-Premises)

When ACCELERO is used in its on-premises version, additional configurations are possible (and necessary) for its correct operation.

Modalities

This chapter applies only to the on-premises modality. In the SaaS modality, these configurations are managed by IONGRADE.

Navigation path: Advanced > System > Accelero Server

Initial Server Configuration​

This section describes the complete first-time configuration procedure of a newly received on-premises server, from defining the IP to accessing the system through the browser.

Step 1: Define the Server IP​

The on-premises server does not require an internet connection, but it needs a local connection between the controllers and the computers that will access ACCELERO.

To configure the IP:

  1. Connect a monitor and a USB keyboard to the server.
  2. Turn on the server using the power supply shipped with the equipment.
  3. On the monitor, enter the maintenance credentials:
    • User: manutencao
    • Password: manutencao
  4. Go to the network configuration menu and adjust the IP according to the installation's needs.
The password does not appear on the screen

When typing the password, Linux does not display the characters. This behavior is normal — continue typing and confirm.

Fixed IP recommended

The server comes configured in DHCP by default, but we always recommend using a fixed IP to ensure that controllers and operators always find the server. Note the IP defined, as it will be used in the following steps.

Step 2: Install the Digital Certificate in the Browser​

The digital certificate must be installed on each computer that will access the system. The recommended browser is Google Chrome.

  1. In the browser, go to the certificate path, replacing the IP with the IP defined in Step 1:

    http://192.168.0.10/certs/accelero.crt

    The certificate download starts automatically.

  2. Double-click the downloaded file and click Install Certificate.

    Windows Certificate dialog with the Install Certificate button

  3. Advance through the import wizard, select the Place all certificates in the following store option, and click Browse.

    Certificate import wizard — step 1

    Certificate import wizard — step 2

  4. Select Trusted Root Certification Authorities and confirm.

    Certificate import wizard — step 3

  5. Complete the wizard.

    Certificate import wizard — step 4

Step 3: Edit the hosts File​

The last step associates the server IP with the name accelero on the accessing computer.

  1. Go to the C:\Windows\System32\drivers\etc directory and locate the hosts file.

    hosts file in the Windows etc folder

  2. Copy the hosts file to the desktop — this avoids damaging the original during editing.

  3. Right-click on the copy and select Open with > Notepad.

  4. Add a line with the IP defined in Step 1 followed by the name accelero:

    192.168.0.10  accelero

    hosts file edited in Notepad

  5. Save without changing the file format (do not add a .txt extension).

  6. Copy the edited file back to C:\Windows\System32\drivers\etc, replacing the existing file.

Step 4: Access the System​

With the procedures completed, the on-premises server is configured and ready for use. Access ACCELERO at the address:

https://accelero
Why the name "accelero"?

Editing the hosts file lets you access the system by a friendly name (https://accelero) instead of the IP. The certificate installed in Step 2 is issued for that name — that is why access only works correctly with hosts and certificate configured.

Available Configurations​

The on-premises server has 4 configuration tabs:

  1. Network - IP, gateway, and DNS configuration
  2. Disk usage - Space monitoring
  3. Email - SMTP server for sending emails
  4. Remote access - IONGRADE technical support

1. Network​

Configuration of the IP address and connectivity of the server.

Tab: Network

IP Configuration​

Two options available:

Use DHCP​

When to use:

  • Network with a reliable DHCP server
  • Dynamic environment
  • Testing and staging

Configuration:

  1. Select "Use DHCP"
  2. Save
  3. The server will obtain an IP automatically

When to use:

  • Production (always!)
  • Controllers need to access the server
  • Stability required

Configuration:

  1. Uncheck "Use DHCP"
  2. Enter:
    • IP address: Fixed IP of the server
    • Network mask: Subnet mask (e.g., 255.255.255.0)
    • Gateway: Network gateway
    • DNS server: DNS server for name resolution
Changing the Network Mask

You can change the server's network mask directly through the interface, without needing access to the operating system.

Example:

IP address: 192.168.1.100
Gateway: 192.168.1.1
DNS: 192.168.1.1 or 8.8.8.8
IONGRADE Recommendation

Always use a fixed IP in a production environment to ensure that controllers and operators always find the server.

Server Controls​

On the same Network tab, the following are available:

Control buttons:

ButtonActionWhen to Use
RestartRestarts the serverAfter critical changes, troubleshooting
Shut downShuts down the serverPhysical maintenance, relocation
Operational Impact

Restarting or shutting down the server interrupts all accesses. Plan it for low-traffic hours!

Change via Interface vs. Equipment​

You can configure the IP in two ways:

  1. Via the interface (this screen) - Easier and recommended
  2. Directly on the equipment - Physical/console access

Both are valid, but the web interface is more convenient.

2. Disk Usage​

Monitoring of the disk space used by the system.

Tab: Disk usage

Client's Responsibility​

In the on-premises version, disk space management is up to the user.

Displayed Information​

The screen shows:

  • Total disk space
  • Used space
  • Available space
  • Usage percentage
  • Top consumers of space

Top Consumers​

Two items are the largest contributors to disk usage:

1. Database​

What it takes up:

  • Event logs
  • Operation logs
  • Access history
  • Registration data

How to clean:

Path: Advanced > Maintenance > Log deletion

See Maintenance for the complete procedure.

2. People Photos​

What it takes up:

  • Registered facial photos
  • Visitor photos
  • Camera captures

How to clean:

Path: Advanced > Maintenance > Photo deletion

Delete photos of disabled people or old visitors.

Plan Capacity

Monitor disk usage regularly. A full disk can interrupt system operation!

Best Practices​

  1. Monitor weekly: Check the usage percentage
  2. Set alerts: Configure a notification when the disk reaches 80%
  3. Clean periodically: Old logs and photos should be deleted
  4. Back up first: Always before deleting data massively
  5. Plan for expansion: If growth is constant, expand the disk

3. Email​

Configuration of the SMTP server for sending emails by the system.

Tab: Email

Client's Responsibility​

In the on-premises version, it is the user's responsibility to specify an email server.

When Emails Are Sent​

ACCELERO sends emails for:

  • Invites to new operators
  • Password recovery
  • QR Codes for visitors
  • Check-in notifications
  • System alerts

Without a configured SMTP server, these functions will not work.

Configuration​

Available fields:

FieldDescriptionExample
SMTP serverServer addresssmtp.gmail.com
PortConnection port587 (TLS) or 465 (SSL)
UserLogin for authenticationsistema@empresa.com
PasswordUser's password**********
Use TLS/SSLEncryption✓ Enabled
SenderName that appears in the emailsACCELERO - Company XYZ
Sender emailOrigin addressnoreply@empresa.com

Configuration Examples​

Gmail​

Server: smtp.gmail.com
Port: 587
Use TLS: ✓ Yes
User: your-email@gmail.com
Password: app-password (not the normal password!)
App Password

Gmail requires an app password, not the account password. Configure it in Google's security settings.

Office 365​

Server: smtp.office365.com
Port: 587
Use TLS: ✓ Yes
User: your-email@company.com
Password: your-password

Own Server​

Server: mail.company.com
Port: 25 (or according to your server)
User: accelero@company.com
Password: configured-password

Send Test​

After configuring, test the sending:

  1. Try password recovery for an operator
  2. Check whether the email arrived
  3. Validate that the content is correct
Documentation

Consult your email provider's documentation for specific SMTP settings.

4. Remote Access​

Allows the IONGRADE team to access the server remotely for technical support.

Tab: Remote access

Security​

Remote access is highly secure:

  • Requires an encrypted key provided by IONGRADE
  • The client must enter the key manually
  • The client must request access explicitly
  • Without the client's consent, access is impossible
Privacy Guaranteed

IONGRADE never accesses the server without the client's express authorization.

When to Use​

Remote access is necessary for:

  • Specialized maintenance
  • System updates
  • Complex troubleshooting
  • Advanced technical support

How It Works​

  1. Client contacts IONGRADE support
  2. IONGRADE generates an encrypted key
  3. IONGRADE sends the key to the client (email, WhatsApp, etc.)
  4. Client goes to the Remote access tab
  5. Client enters the key in the "Key for remote access" field
  6. Client clicks "Request remote access"
  7. Connection is opened - IONGRADE can access
  8. Work is performed
  9. Connection is closed at the end

Step by Step​

  1. Receive the key from IONGRADE (example):

    7f4a9c2e8b1d6f3a9e5c8d2b4f7a1e6c

  2. Go to Advanced > System > Accelero Server > Remote access tab

  3. Paste the key in the "Key for remote access" field

  4. Click "Request remote access"

  5. Wait for IONGRADE to perform the work

  6. The connection closes automatically after completion

Key Validity

Keys have limited validity. Use them right after receiving them from IONGRADE.

Best Practices​

  1. Always a fixed IP: Use a fixed IP in production

  2. Monitor the disk: Check usage weekly

  3. Configure email: Essential for full operation

  4. Document configurations: Keep a record of IP, gateway, DNS

  5. Test after changes: Validate connectivity after changing the network

  6. Regular backup: Back up before critical changes

  7. Update regularly: Keep the server up to date

  8. Monitor logs: Track the operating system logs

  9. Protect physically: Server in a secure, climate-controlled location

  10. Controlled access: Only authorized personnel should access the server

Troubleshooting​

Server does not respond after changing the IP​

Cause: IP configured incorrectly

Solution: Access the physical console, reconfigure the IP

Emails are not sent​

Causes:

  • Incorrect SMTP server
  • Invalid credentials
  • Port blocked by firewall

Solution: Check the configurations, test SMTP connectivity

Full disk​

Cause: Accumulated logs and photos

Solution: Run cleanup via the Maintenance menu

Remote access does not work​

Causes:

  • Expired key
  • Key typed incorrectly
  • Firewall blocking

Solution: Request a new key, check the typing, unblock the firewall
