Installing Modules in the Unit
To insure proper installation, complete the following:
1. Power OFF the NH2025-10 switch.
2. Carefully slide an NH2025-10 module into a free dport and press firmly to insert.
3. Tighten the thumbscrews securely.
4. Power ON the NH2025-10 switch. If you have a flash version lower than 1.20 and you are
installing F/O modules, you must download a new software version to the switch so that the
firmware recognizes the new uplinks and the modules operate correctly.
