Smart ZPHA Module Hardware
The Smart ZPHA modules include a set of relays for receiving network traffic from a network device, routing the traffic through the device, and sending it back out to a network device. The network device could be an Ethernet switch, a single workstation, a server, or other network service. The Smart ZPHA module receives power through the TippingPoint device in which it is installed. If the power is interrupted due to power supply failure, power loss, or unplugging, the module continues to pass traffic through the network while bypassing the device. Smart ZPHA modules may be single-mode or multi-mode. Be sure to select the module type that is suitable for your network.
Smart ZPHA Module Installation
When you install the Smart ZPHA module, you need the following components:
- Two single-mode or multi-mode fiber network cables as required for your network and your Smart ZPHA module.
- Two straight-through short fiber cables to connect the module to the TippingPoint device. These cables are supplied with the Smart ZPHA module.
WARNING: Handle the ZPHA module with care. The ZPHA module contains optical switches that are very sensitive to handling when not installed in the system. Loss of data may occur if handled improperly. The ZPHA module can only be hot-swapped with supported software releases. For proper operation the ZPHA module should be installed with the device powered down.
How To: Install the Smart ZPHA Module
1. Remove the blank faceplate from the module bay.
2. Slide the Smart ZPHA module into the module bay.
3. Turn the screw located at the bottom of the module with a Phillips screwdriver to lock the module in the port.
Initializing the Smart ZPHA Module
Once the Smart ZPHA module is installed in your TippingPoint device, the device must be properly initialized. If the module is not initialized, it may not pass traffic from one device to the other.
1. With the module installed, power on and boot the TippingPoint device.
2. Wait for the device to complete the boot process.
When the boot process is complete, the Smart ZPHA module will perform correctly. This process ensures that the module capacitors are fully charged and provide enough power to enable bypass operation when power loss occurs.
Connect Fiber Cables
1. For each Smart ZPHA module, connect the fiber network cables to your network. Be sure to match the transmit (TX) and receive (RX) cables correctly.
2. Connect the short cables to the Smart ZPHA module and to the device. Refer to the following diagram.
Tip: The activation of the Smart ZPHA module may result in a link transition where a link goes down and then up. Even though ZPHA switching is extremely fast, certain network equipment can take longer to establish a link. You should take note of required link times of the network equipment connected to the Smart ZPHA module.
