Management Ethernet Port Pinouts

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

Note

This is not a data plane port.

The table below summarizes the Management Ethernet port pinouts.

USB Console Port Pinouts

Two individual Type A USB connectors are used for the USB console and USB mass storage. One USB 2.0 Type A receptacle is provided on the RSP front panel for providing console access to ROMMON, Cisco IOS-XE, and diagnostics. This USB 2.0 Type A receptacle operates as a USB peripheral only for connections to an external host PC. This receptacle 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. When 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, and so on, and supports up to 12 Mbps of operation.

The table below summarizes the USB console port pinouts.

Table 14. Single USB Console Port Pinout
Pin	Signal Name	Description
A1	Vcc	+5 VDC (500 mA)
A2	D-	Data -
A3	D+	Data +
A4	Gnd	Ground

Note

The USB console port supports +5 VDC input, and operates as a USB peripheral device.

USB Flash or MEM Port Pinouts

The table below summarizes the USB flash or MEM port pinouts.

Pin	Signal Name	Description
A1	Vcc	+5 VDC (500 mA)

Note

USB TYPE-A receptacle is used.

Note

The USB flash or MEM port +5VDC is output. Cisco ASR 902 Router provides power for USB flash or MEM port. This port 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.
