Management Ethernet Port Pinout

A single management copper ENET port supporting 10/100/1000Base-T operation exists on each RSP. There is no direct access to the CPU of the other RSP. It uses a standard RJ45 jack.

Note

This is not a data plane port.

The table below summarizes the Management Ethernet port pinout.

USB Console Port Pinout

Two individual Type-A USB connector are used for USB console and USB mass storage. One single USB 2.0 Type-A receptacle is provided on the RSP front panel for providing console access to ROMMON, IOS-XE and diagnostics. It operates as a USB peripheral only for connection to an external host PC. This requires the use of a Type-A to Type-A connector instead of a standard USB cable.

Note

The use of the USB console is mutually exclusive with the RS232 console/Aux port. While a USB cable is inserted, access is automatically switched to this port.

The other single USB 2.0 Type-A receptacle is provided on the RSP front panel for inserting external USB mass storage devices such as standard USB flash drives. It is used to load images, store configurations, write logs, etc. It supports operation up to 12Mbps

The table below summarizes the USB console port pinout.

Table 15. Single USB Console Port
Pin	Signal Name	Description
A1	Vcc	+5VDC (500mA)
A2	D-	Data -
A3	D+	Data +
A4	Gnd	Ground

Note

The USB Console port +5VDC is input and operates as an USB peripheral device.

USB Flash/MEM Port Pinout

Note

The USB flash/MEM port +5VDC is output. We provide power for USB flash/MEM, and it operates as a USB host device.

Fiber-Optic Specifications

The specification for optical fiber transmission defines two types of fiber: single-mode and multimode. Within the single-mode category, three transmission types are defined: short reach, intermediate reach, and long reach. Within the multimode category, only short reach is available. For information about optical SFP modules, see the documentation for the SFP module at

http://www.cisco.com/en/US/partner/products/hw/modules/ps5455/prod_installation_guides_list.html.

Cabling Guidelines

The guidelines are recommended during the installation of fiber cables:

Avoid the following actions that can stress the cable:
- Pulling or stretching beyond the specified pulling load rate
- Bending it beyond the specified bend radius
- Creating tension in the suspension runs
Do not touch the fiber tips of fiber cables.
Use single mode or multi-mode optical fiber cables as per the optical transceiver requirement.
Use fiber cleaner to clean the fiber tip as well as transceiver before inserting the fiber cable into the optical transceiver during installation.
To avoid excessive bending of fiber cable and efficient routing of cables, cable guides or cable brackets are recommended to be used with the chassis.

LED Summary

The following sections describe the meanings of the LEDs on the Cisco NCS 4206.

RSP LEDs

The table below summarizes the RSP LEDs for the supported RSP modules.

Note

A major alarm condition indicates the failure of a single fan in the fan tray; a critical alarm indicates the failure of multiple fans. In the event that a single fan fails, the Cisco NCS 4206 software adjusts the fan speed to prevent excessive heat within the chassis.
