  • Full installer (fresh install): Use for new SEPM servers.
  • Upgrade package: Use when upgrading an existing SEPM (follow upgrade path recommendations).
  • Virtual Appliance / ISO: Available for supported platforms—use if deploying as VM appliance.

5. Installation Walkthrough (High-Level)

  1. Prepare the server – Install Windows Server, static IP, disable Windows Defender temporarily.
  2. Install SQL Server – SQL Express is fine for <500 endpoints.
  3. Run SEPM installer – Choose “Install Management Server” (not “Management Console only”).
  4. Database configuration – Point to your SQL instance, create a new SEPM database.
  5. Web server settings – IIS is optional but recommended for reporting.

  9. LiveUpdate setup – Configure internet or internal update source.

Q4: My download keeps failing at 99%. Why?

A: This is typically an antivirus or proxy timeout. Disable real-time scanning on your download machine temporarily. Alternatively, use a CLI download tool like wget or curl to bypass browser limitations.

Post-Installation: Deploying the 14.3 Client

The manager is useless without clients. Use your downloaded manager to push the 14.3 agent:

  1. Login to the SEPM console (https://localhost:8443).
  2. Navigate to Admin > Install Packages.
  3. Choose "Export Client Install Package".
  4. Set the package type (Windows 64-bit) and select "Embed the communications security certificate."
  5. Deploy via Group Policy, SCCM, or a simple login script.

6) Common troubleshooting

  • Installation fails: check installer logs (SEPM install logs), verify prerequisites (OS patches, .NET, DB connectivity).
  • Clients not checking in: confirm firewall rules, ports (usually 8443/8446 for SEPM communications), and that client packages match SEPM version.
  • Upgrade issues: ensure supported upgrade path (consult Broadcom KB), uninstall incompatible third-party software, and verify DB compatibility.
  • If problems persist, collect logs and contact Broadcom support.
