Bypass Modules (BPS-HC1-D25A60 SX/SR, BPS-HC1-D35C60 LX/LR)

The BPS-HC1-D25A60 is multi-mode SR and BPS-HC1-D35C60 is single-mode LR 1Gb/10Gb bypass modules. Bypass Modules offer six inline network port pairs each.

Before installing a Bypass Module, the GigaVUE‑HC1-Plus must be running on the software version 6.00 or higher. For internal transceiver and loss summary specifications, refer to Bypass Module Specifications.

The GigaVUE‑HC1-Plus offers physical and logical inline bypass. Physical bypass provides automatic failover protection in the case of a power failure. The bypass modules provide the physical bypass function. As it applies to a single pair of inline network ports, the physical bypass function is as follows:

  • When the module is not powered, (either the entire node is powered down or the module is removed from the node), the inline network port pair is in the physical bypass mode. That means that traffic is exchanged directly between network Port A and network Port B of the inline network pair.

  • When the module is powered, the mode (inline or bypass) of the inline network port pair is controlled through software. In the physical bypass mode, the inline network port pair behaves exactly as if the module was not powered. In the inline mode, the inline network port pair behaves as any other inline network port pair configured for working with an inline tool.

Features of the 10Gb Bypass Modules:

■   Six inline network port pairs that pass traffic bi-directionally.
■   Port pairs that offer optical protection switch for physical bypass.
■   A mode to select either bypass or inline.
■   A module that is hot swappable. Refer to procedures in Module Removal and Replacement Procedure (Hot Removal).

Module Status LEDs

The following module status LEDs are located on the front of the bypass modules:

■   RDY is the Ready LED. It has the following states:
o   RED indicates system booting or module down
o   GREEN indicates normal condition
■   POWER is the Power LED. It has the following state:
o   GREEN indicates the module is receiving power

Inline Network Ports

Connect inline networks to the inline network ports. The inline network ports have built-in protection for power down.

The inline network status LEDs have the following labels:

• A—Inline network LED A

• B—Inline network LED B

• M—Mode LED (on is inline and off is bypass)

Using Bypass Modules for Gigamon Resiliency for Inline Protection

■   Gigamon Resiliency for Inline Protection (GRIP)™ is an inline bypass solution that connects two GigaVUE‑HC1-Plus nodes together so that one node provides high availability to the other node when there is a loss of power. This redundant arrangement of two GigaVUE‑HC1-Plus nodes maintains traffic monitoring by inline tools when one of the nodes is down.
■   GRIP™ makes use of the bypass protection switch relays for protected inline networks on GigaVUE‑HC1-Plus nodes. The bypass modules can provide physical protection for protected pairs of optical inline network ports required by the GRIP solution.
■   To configure the GRIP solution, the GigaVUE‑HC1-Plus must be running GigaVUE-OS version 6.0 or higher. For solution and configuration information, refer to the chapter “Configuring Inline Bypass Solutions” in the GigaVUE-OS-CLI Reference Guide.
