CH A P T E R 4 WAVE Inline Network Adapter This chapter describes the Cisco WAVE inline network adapter and contains the following sections: • Inline Network Adapter Description, page 4-1 • Ports and LED Indicators, page 4-3 • Inline Network Adapter Cabling Requirements, page 4-4 • Installation Scenarios and Cabling Examples for Fast Ethernet Connections, page 4-7 For adapter specifications, see Table A-2 in Appendix A, “Wide Area Virtualization Engine Hardware Specifications”.
Chapter 4 WAVE Inline Network Adapter Inline Network Adapter Description Note Throughout this section, we refer to a WAVE appliance configured for inline interception mode as a WAVE inline appliance. The WAAS software defines two new interface types: A group interface that represents an inline pair grouping and a port interface that represents the individual port. These interfaces are referred to as inlineGroup and inlinePort. InlineGroup interfaces are numbered using the format slot/group.
Chapter 4 WAVE Inline Network Adapter Ports and LED Indicators Ports and LED Indicators Figure 4-1 shows the 2-port inline network adapter port numbers, interface designations, and LEDs.
Chapter 4 WAVE Inline Network Adapter Inline Network Adapter Cabling Requirements Inline Network Adapter Cabling Requirements The inline network adapter ships with two types of cables: crossover and straight-through. When you connect the WAVE inline network adapter, the cable that you use depends on the link speed (Gigabit Ethernet or Fast Ethernet) and the types of devices (DCE or DTE) being connected. Note You must retain the same link speed from one end of the connection to the other end.
Chapter 4 WAVE Inline Network Adapter Inline Network Adapter Cabling Requirements Table 4-2 Cable Requirements for WAVE Connections Using Gigabit Ethernet (continued) Connection Required Cable Router to WAVE and Crossover or straight-through WAVE to Router Crossover or straight-through WAVE to WAVE Crossover or straight-through Some switches support automatic medium-dependent interface crossover (MDIX). You can configure MDIX by using the mdix auto global configuration switch command.
Chapter 4 WAVE Inline Network Adapter Inline Network Adapter Cabling Requirements Note Because the inline network adapter has an internal crossover connection that becomes active when the InlineGroup interface is placed in mechanical bypass mode, you must decide which cable you would use to connect the two network devices directly, and then you must install the other cable type (on one side, usually the WAN side of the inline appliance) instead.
Chapter 4 WAVE Inline Network Adapter Installation Scenarios and Cabling Examples for Fast Ethernet Connections For example, if you are connecting a router and a switch (two different devices) through the WAVE inline appliance, use a straight-through cable on the LAN side of the connection and use a crossover cable on the WAN side of the connection. (If you were connecting the two different devices directly, you would use a straight-through cable, so use the crossover cable instead.

Appendix B Maintaining the Wide Area Virtualization Engine Maintaining Your Site Environment • Clean the system at regular intervals to avoid any buildup of dust and debris, which can cause a system to overheat. • If the system has been exposed to abnormally cold temperatures, allow a 2-hour warm-up period to bring it up to a normal operating temperature before turning it on. Failure to do so may cause damage to internal components, particularly the hard disk drive.
Appendix B Maintaining the Wide Area Virtualization Engine Maintaining Your Site Environment Dust and Particles A clean operating environment can greatly reduce the negative effects of dust and other particles, which act as insulators and interfere with the operation of a system’s mechanical components. In addition to regular cleaning, you should follow these guidelines to deter contamination of the system equipment: • Do not permit smoking anywhere near the system.
Appendix B Maintaining the Wide Area Virtualization Engine Maintaining Your Site Environment • Wear a grounding wrist strap. If a grounding wrist strap is unavailable, touch an unpainted metal surface on the chassis periodically to neutralize any static charge. • Keep components in their antistatic packaging until they are installed. • Avoid wearing clothing made of wool or synthetic materials.
Appendix B Maintaining the Wide Area Virtualization Engine Maintaining Your Site Environment • Printers • Telephones with real bells • Fluorescent lights Shock and Vibration Excessive shock can damage the function, external appearance, and physical structure of a system. Each system has been designed to operate properly even after withstanding a minimum of six consecutively executed shock pulses in the positive and negative x, y, and z axes (one pulse on each side of the system).
Appendix B Maintaining the Wide Area Virtualization Engine Using Power Protection Devices – Teletype machines – Adding machines – Laser printers – Facsimile machines – Any other motorized equipment Besides these appliances, the greatest threats to a system’s supply of power are surges or blackouts caused by electrical storms. Whenever possible, turn off the system and any peripherals and unplug them from their power sources during thunderstorms.
Appendix B Maintaining the Wide Area Virtualization Engine Using Power Protection Devices Line Conditioners Line conditioners go beyond the overvoltage protection of surge protectors. Line conditioners keep a system’s AC power source voltage at a fairly constant level and therefore can handle brownouts. Because of this added protection, line conditioners cost more than surge protectors—up to several hundred dollars. However, these devices cannot protect against a complete loss of power.
