The USB 3.0 Type A port provides access to external USB flash devices (also known as thumb drives or USB keys). The port supports Cisco USB flash drives with capacities from 64MB to 16GB. USB devices with port densities of 64 MB, 128 MB, 256 MB, 1 GB, 4 GB, 8 GB, and 16 GB are supported. The port provides 2.5 W of power to the device connected to the port.

Cisco IOS software provides standard file system access to the flash device, such as read, write, erase, and copy, as well as the ability to format the flash device with a FAT file system.

The USB drive provides you with the ability to automatically upgrade the internal flash with the USB drive's configuration and image for emergency switch recovery using the USB auto upgrade feature. This feature checks the internal flash for a bootable image and configuration, and if either the image or the configuration is not available, the USB drive is checked for boot image and configuration. If the boot image and configuration are available, these are copied to flash for the reboot.

Observe these guidelines when using USB flash drives:

• There must be at least one partition on the USB flash drive. If the drive has more than one partition, only the first partition is visible in the system (Cisco IOS).

• If you partition the flash drive, we recommend that you use a Linux system to perform this task. This ensures that the first partition is a usable partition when connected to the switch.

  Using a Windows or MacBook machine utility to perform this task may result in two partitions on the drive by default (partition for system information + actual usable partition). When such a flash drive is connected to the switch, the system displays only the first system information partition, and not the actual usable partition.

The supervisor module provides two types of console ports on the supervisor module front panel:

• RJ45 console port: This port provides universal asynchronous receiver/transmitter (UART) support to access the route processor with a serial console running at 9600 baud rate with 8 bits for data, no parity bit, and 1 stop bit.

• Mini USB 2.0 Type B console port: This port functions as a second console connection to the route processor. The USB console port connection uses a mini USB 2.0 cable. The USB console interface speed is the same as the RJ45 console interface speed.

Only one of the consoles is active at a time. When a USB host (PC) is plugged into the USB console port, the hardware automatically switches over to use the USB console. Only a PC that has the necessary USB console device driver causes the USB console to become active. Plugging in a PC that does not have the USB console driver support does not cause a switchover. When the USB cable is removed, or the PC deactivates the USB connection, or a host is not detected on the USB console, the hardware automatically switches to the RJ45 console interface.

The console port allows you to perform the following functions:

• Configure the switch from the CLI

• Monitor network statistics and errors

• Configure SNMP agent parameters

The Supervisor Module provides two types of management ports, 10/100/1000BASE-T RJ-45 port and 10G SFP+ port. The RJ-45 and SFP+ management ports provide out-of-band (OOB) Ethernet network connectivity, which enables you to use the CLI to manage the switch using its IP address. A management port supports TFTP image downloading, network management, SNMP, Telnet, and SSH connections.

• SFP+ management port: This port is a fiber port that is referred to as TenGigabitEthernet<slot>/0/<port>. The C9600-SUP-1 module has one SFP+ port that supports 1G and 10G speeds. The C9600X-SUP-2 module has two SFP+ ports in which only one port is used for management. The SFP+ ports on C9600X-SUP-2 support only 10G speed.

• Ethernet management port: This port is a copper Ethernet port that is referred to as GigabitEthernet0/0( Gi0/0) port. The Ethernet management port supports speed upto 10/100/1000 Mbps and is set to auto-negotiate.

You can use one of these ports depending on the cable and connectors that you are using to connect the management interface to the network. Use only one of these management ports; the switch does not support the use of both management ports. By default, the Ethernet management port is enabled.

Use the management port instead of the console port for network management. A switch cannot route packets from a management port to a network port, and from a network port to a management port. To obtain this, the management interface is automatically placed in a separate routing domain (or VRF domain), called Mgmt-vrf. The devices support out-of-band (OOB) management through Mgmt-vrf, which is used to segment management traffic from the global routing table of the switch.

When managing a switch, connect the PC to the management port of the supervisor engine.

A recessed access button is available on the front panel of the supervisor module to reset and restart the module. Using a pin, press and hold the button inwards for 5 seconds to reset and restart the module.

Warning

The covers are an integral part of the safety design of the product. Do not operate the unit without the covers installed. Statement 1077

ESD damage might occur when modules or other FRUs are improperly handled, resulting in intermittent or complete failure of the modules or FRUs. Modules consist of printed circuit boards that are fixed in metal carriers. EMI shielding and connectors are integral components of a carrier. Although the metal carrier helps to protect the board from ESD, always use an ESD-grounding strap when handling modules. To prevent ESD damage, follow these guidelines:

• Always use an ESD wrist or ankle strap and ensure that it makes good skin contact.

• Connect the equipment end of the strap to an unfinished chassis surface.

• When installing a component, use an available ejector lever to properly seat the bus connectors in the backplane or midplane. These devices prevent accidental removal, provide proper grounding for the system, and help to ensure that bus connectors are properly seated.

• When removing a component, use an available ejector lever to release the bus connectors from the backplane or midplane.

• Handle carriers by available handles or edges only; avoid touching the printed circuit boards or connectors.

• Place a removed component board-side-up on an antistatic surface or in a static-shielding container. If you plan to return the component to the factory, immediately place it in a static-shielding container.

• Avoid contact between the printed circuit boards and clothing. The wrist strap only protects components from ESD voltages on the body; ESD voltages on clothing can still cause damage.

• Never attempt to remove the printed circuit board from the metal carrier.

You will need these tools to install or remove supervisor engines and line cards:

• Your own ESD-prevention equipment or the disposable grounding wrist strap included with all upgrade kits, FRUs, and spares.

• Antistatic mat or antistatic bag
