Disable Bypass Relays

To implement direct standby operation, you must modify the motherboard to disable the normal bypass relay function of a powered-down PacketShaper. In a typical installation, if a unit fails or loses power, relays close to allow user traffic to pass unhindered between the two ports. As a component of a redundant configuration, however, a powered-down PacketShaper needs to be a point of failure in the network. Therefore, disabling the bypass functionality ensures that an out-of-service, failed, or powered-down unit does not pass traffic.

For instructions on disabling bypass relays, see the appropriate section for your model:

2500, 3500, 6500, 7500, 9500, 10000

Notes:

• PacketShapers with fiber-optic connectors do not need to be modified, and the Packeteer Fiber Bypass Switch should not be deployed.
• If you plan to deploy PacketShaper 1400 models in a direct standby configuration, please contact Packeteer Customer Support for assistance.
• Because the PacketShaper models 1200, 1550, and 1700 don’t have expansion slots and can’t accommodate a LAN Expansion Module, you will not be able to use the direct standby feature on these models.
