Link Continuity

Figure 3-9 Optical Bypass Under Normal Operating Conditions

If the SCE8000 platform fails, traffic flows through the optical bypass module, bypassing the SCE8000,

so that traffic on the link is maintained

Figure 3-10 Optical Bypass Under Failure Conditions

Note In cascade configuration, installation of the optical bypass module is required

This optical bypass module can be added to link without altering the basic characteristics of the

topology. (The installation procedure and the actual connections are somewhat different when the

optical bypass module is used, see Optical Bypass Module Connectivity, page 6-8.)

For more information regarding the external bypass module, refer to The Cisco SCE8000 Optical

Bypass, page 2-8.
