- Rack shelf
- for Aruba 5406 zl
The HP zl Power Supply Shelf provides additional Power over Ethernet (PoE) power to a zl switch beyond what can be provided by the switch's internal power supplies alone. The power supply is rack mountable and has two slots for zl switch power supplies. A large VoIP installation provides an ideal environment for the power shelf, particularly if a high level of PoE power redundancy is desired.
