APC Network Management Card Firmware Upgrade

This repository automates firmware upgrades for APC Network Management Cards (NMCs) over SFTP using Python and Paramiko.

Files in this repository

• update_firmware.py
  Main script: discovers firmware binaries, reads device list, and uploads AOS and SUMX images with concurrency.
• credentials.example.json
  Copy to credentials.json and fill with your SFTP credentials.
• device_list.csv
  One IP address per line under header IP.
• .gitignore
  Excludes credentials.json and the firmware directory.

Note: The firmware directory (apc_hw05_aos720_sumx720_bootmon109/) and its contents are not included in this repo.

Requirements

• Python 3.x
• Paramiko (pip install paramiko)

---

Configuration

1. Copy credentials.example.json to credentials.json:

   {
     "sftp_username": "your_username",
     "sftp_password": "your_password",
     "sftp_port": 22
   }

2. Populate device_list.csv:

   IP
   192.168.1.100
   192.168.1.101

3. Ensure your firmware binaries are in a local folder (e.g., .../Bins) matching file patterns *aos*.bin and *sumx*.bin.

---

Usage

Run the script with:

python update_firmware.py --fw-dir /path/to/apc_hw05_aos720_sumx720_bootmon109/Bins

The script will:

1. Read SFTP credentials and device IPs
2. Locate AOS and SUMX binary files
3. Upload AOS to each device, wait for reboot, then upload SUMX
4. Process 5–10 devices concurrently

---

Concurrency

• Uses a thread pool with a minimum of 5 and maximum of 10 workers.

---

Logging

• Uses Python’s logging module to output timestamps, log levels, and device-specific messages to the console.
