Pairing a Smart PDU with Syaccess CMP (Self-Hosted)

This guide walks you through pairing each Smart PDU with your Synaccess CMP deployment.

What you need

• Cloud URL of your deployment
  • Example: https://cmp.yourdomain.com (preferred) or http://cmp.internal.local
  • Know whether you run HTTPS or HTTP.
• Cloud admin username and password (created during initial setup).
• PDU IP address that you can reach directly from your workstation.
• Network egress from the PDU to your Cloud URL (port 443 for HTTPS, 80 for HTTP).
• If using HTTPS with a private or non-default CA, have the CA certificate in PEM (.crt/.pem) ready.

Pairing steps

1. Log in to the PDU

   • Browse to the PDU’s IP (e.g., http://10.10.10.25/) and sign in.

   • 
     

2. Open the pairing page

   • Go to Network → Self-Hosted.

1. Enable the feature

   • Toggle Enable Self-Hosted Management Connection → Save.

2. (HTTPS only) Configure certificate trust – recommended

   • See “TLS certificate options” below. If you run HTTPS, upload the appropriate CA and enable Validate Host Certificate.

3. Enter your Cloud URL

   • In URL, enter your deployment URL exactly (no extra paths).
     • Examples:
       • https://cmp.yourdomain.com
       • http://cmp.internal.local:8080 (custom port)

4. Enter Cloud credentials

   • Username and Password = your Synaccess CMP admin account.

5. Pair

   • Click Pair Device and wait for confirmation.

6. Verify in Synaccess CMP

   • Sign in to Synaccess CMP → Devices/PDUs. Confirm the PDU appears as online/healthy.
   
   

Repeat these steps for each PDU you want to manage.

TLS certificate options in the PDU UI

In Self-Hosted Configuration you’ll see:

• Validate Host Certificate (toggle) When ON, the PDU verifies TLS for your Cloud URL: issuer trust, certificate expiry, and hostname match. This is the recommended production setting.

• Upload CA Certificate (button) Lets you add the issuing CA certificate so the PDU can trust your server certificate chain.

Important: Use a hostname in the Cloud URL that matches the certificate’s CN/SAN. Pairing will fail if you use an IP address but your certificate is issued for a DNS name.

Recommended sequence for HTTPS

1. Click Upload CA Certificate and select the CA (PEM text or .crt/.pem).
2. Toggle Validate Host Certificate ON → Save.
3. Enter the https:// URL, username, and password → Pair Device.

Troubleshooting

• “TLS/Certificate” errors
  • Ensure Validate Host Certificate is ON only after uploading the correct CA.
  • Confirm the hostname in the URL matches the certificate. Avoid IP addresses with hostname-only certs.
  • Check device date/time; large clock drift will break TLS.
• Device doesn’t appear in Synaccess CMP
  • Verify outbound access from the PDU to your Cloud URL (firewall, proxy, NAT).
  • Re-enter credentials; ensure the account is active and has pairing rights.
• Using HTTP works but HTTPS fails
  • This indicates a trust or hostname issue—upload the correct CA and use a matching hostname, then re-enable validation.

Summary

1. Log in to the PDU → 2) Network → Self-Hosted → 3) Enable and Save →
2. (HTTPS) Upload CA and Validate Host Certificate → 5) enter Cloud URL + credentials → 6) Pair Device → 7) verify in Synaccess CMP.

Repeat for every PDU in your fleet.
