ZPHA Hardware Overview
The ZPHA is a chassis with five available segment ports for module fiber and copper components. These segment modules include a set of relays for receiving and sending network traffic from a network system, into the IPS device, and back out to a network system. The network system could be an Ethernet switch, a single workstation, a server, or other network service. The following table lists the chassis components.

USB ports (2) | USB ports for connecting to the IPS. 2 USB ports (1 type A and 1 type B) are |
| located on the back panel. |
|
|
Segments (5) | Each modular segment includes network ports and segment ports. The |
| segment ports connect to the segment ports of the IPS. The network ports |
| connect to the networked systems sending and receiving traffic via the device. |
| The modular ZPHA supports fiber and copper segment modules. |

The ZPHA receives power through the USB connection to the IPS. If the power through the USB cable interrupts due to power supply failure, power loss, or unplugging, the ZPHA instantly switches to route network traffic, bypassing the IPS connections. It provides two USB ports for connecting two IPS devices.
Note: If you connect two IPS USB cables to the ZPHA device, the ZPHA will continue to function if one of the devices loses power. The ZPHA bypasses the IPS only if all power from the IPS devices interrupts. If two IPS devices are connected, both would have to lose power to cause the ZPHA to bypass.
The ZPHA can accept network connections for up to five (5) network segments. Each connection area is called a segment. You can insert any combination (up to five) of fiber and copper segment components. Any remaining segment ports can be covered with blank faceplates. At any time, you can order additional modular segment components to add to your modular ZPHA.
Tip: The activation of the ZPHA may result in a link transition in the same way that a link goes down and then up. Even though switching of the ZPHA is extremely fast, certain network equipment can take longer to establish link. You should take note of required link times of the network equipment connected to the ZPHA.
