Questions & Answers
What is the WSIC-4GE-BYPASS 4GE Electric Ports Bypass Card?
The WSIC-4GE-BYPASS is a 4-port Gigabit Ethernet bypass card that provides automatic link bypass in Cisco Integrated Services Routers to maintain network uptime during device or power failures.
What are the key features of the WSIC-4GE-BYPASS?
Key features include four electrical Gigabit Ethernet bypass ports, hardware-based link monitoring, sub-1-millisecond bypass relay switching, and hot-swap capability for zero-downtime maintenance.
Which Cisco routers support the WSIC-4GE-BYPASS card?
The WSIC-4GE-BYPASS is compatible with select Cisco ISR 4000 Series routers equipped with a Wideband Slot Interface Card (WSIC) slot as specified in Cisco’s compatibility matrix.
How do I install the WSIC-4GE-BYPASS card?
Power down your router, open the WSIC slot cover, insert the WSIC-4GE-BYPASS card until it seats firmly, secure the retention bracket, and power the router back on.
Does the WSIC-4GE-BYPASS require additional licensing?
No additional software license is required. The bypass functionality operates at the hardware layer and is automatically enabled upon installation.
How does the bypass mechanism work?
In the event of a loss of power or device failure, onboard relays automatically close to create a direct pass-through of the two affected Ethernet links, preserving network continuity.
How does WSIC-4GE-BYPASS improve network resilience?
By providing sub-millisecond failover at the physical layer, the card prevents link downtime and maintains service delivery when the router or module fails.
What is the maximum throughput per port?
Each of the four electrical Gigabit Ethernet ports supports up to 1 Gbps full-duplex throughput, delivering a combined capacity of 4 Gbps.
What are the power requirements for the WSIC-4GE-BYPASS?
The card is powered entirely by the host router via the WSIC slot and draws less than 5 W during typical operation.
Does the bypass card support link integrity checking?
Yes, it continuously monitors link health using Layer 1 status signals and triggers bypass relays if link failure is detected.
How do I interpret the status LEDs on the bypass card?
Green LED indicates active link, amber LED signals bypass mode, and off means no link or card is unpowered.
Can the WSIC-4GE-BYPASS be used with fiber media converters?
Yes, when paired with media converters that provide electrical Gigabit Ethernet interfaces, the bypass card maintains the same fail-safe behavior.
What are typical use cases for this bypass card?
Common use cases include Metro Ethernet access, WAN edge redundancy, industrial network continuity, and enterprise data-center link protection.
How do I troubleshoot a suspected bypass failure?
Verify LED status, check physical link integrity, confirm router WSIC slot health, and review router system logs for bypass-related events.
What environmental conditions does the WSIC-4GE-BYPASS support?
It operates in 0 °C to 40 °C ambient temperature, 10%–90% non-condensing humidity, and complies with RoHS environmental standards.
What warranty and support are available for the WSIC-4GE-BYPASS?
The card is backed by Cisco’s limited lifetime warranty and includes access to Cisco Technical Assistance Center (TAC) support and software updates.
