IBR Installation Guide (for both user names) is fastback. The same factory-set password will allow a user to enter the Privileged Mode (see the CLI Guide for detailed information). When a user with privileged access changes either of the passwords for the factory-set user names, both factory-set user accounts will be assigned the new password. After login, CLI will be in the User Mode, which offers a limited set of commands. The CLI command prompt in User Mode is the symbol > followed by a space.
IBR Installation Guide 3.6 External Ethernet Connectors IBR has three RJ-45 connectors located on the bottom of the unit, as shown in the illustration in the preceding section. Beginning with the port nearest the LEDs, the Gigabit Ethernet ports are numbered 0, 1, and 2 (ge0, ge1, ge2). All three Ethernet connectors can be used for traffic and IBR management data, but only the one nearest the LEDs (ge0) can power IBR via PoE+.
IBR Installation Guide connecting a power source, position the two IBRs so that they are tilted away from each other, facing downward, and separated by at least one meter. IBR does not have a power on/off switch, either in hardware or software. When power is applied to the unit, IBR will be in a “power on” condition and the system LED beside the ge0 port connector will be illuminated. Apply power to each IBR using a PoE+ source connected to Gigabit Ethernet interface 0.
IBR Installation Guide commands illustrates a way to accomplish this. VLAN2, VLAN823, and the IP addresses shown are used only as examples. (See the CLI Guide for detailed information relating to the VLAN interfaces.) 4.4.1 Configure VLAN Interfaces.

IBR Installation Guide TX BW: 35 MHz RX BW: 35 MHz 5.3 IBR Frequency and Bandwidth: TX: 5300 MHz RX: 5800 MHz TX BW: 35 MHz RX BW: 35 MHz NOTES: These values might be changing as long as RRC is running. The bandwidths do not need to match. From the report, confirm that the two IBRs are compatible. In the example above, the link has one IBR that transmits in the 5.8 GHz band receives in the 5.3 GHz band, and one IBR that transmits in the 5.3 GHz band and receives in the 5.8 GHz band.
IBR Installation Guide If any of these values is outside the required operating range, it might be necessary to reposition (i.e., rotate, elevate, or move) one or both IBRs, or to swap ends of the link. 2.6. Reposition IBR It might be necessary to perform one or more of the following procedures for either or both IBRs. Which repositioning strategy should be tried first will be a decision the field engineer will need to make based on observations at the mounting locations.
IBR Installation Guide By default, all IBR Ethernet ports are assigned natively to VLAN1.
IBR Installation Guide a. Establish communications with IBR via the serial interface ( See the section on communicating with IBR via CLI). b. Confirm that an Ethernet interface is enabled and connected to the network: IBR101 # show interfaces c. If the interface is connected, but not enabled, execute the following commands: IBR101 (config) # interface gigabitethernet 2 where 2 is used as an example (could be 0, 1, or 2).
