Extreme 8720 Switch Hardware Installation Guide

Verify that the device is powered on by verifying that all power LED indicators on the management and interface ports, power supply and fan modules display a steady green light.

Connect the RJ-45 serial cable provided with the device to the management Ethernet port of the device. Shown below are the Port-side views of the 8720 switch:

1 = 40Gbps/100Gbps QSFP+/QSFP28 Ethernet ports	2 = RJ45 serial console port
3 = Status LEDs	4 = Type A USB storage port
5 = RJ-45 out-of-band 10/100/1000BASE-T management Ethernet port MGMT2 - CPU and BMC (secondary)	6 = RJ-45 out-of-band 10/100/1000BASE-T management Ethernet port MGMT1 - Direct to CPU (primary)

Note

The console or serial port is intended primarily for the initial setting of the IP address.

Access the device using a terminal emulator application (such as HyperTerminal in a Windows environment or Tip in a LINUX environment).

Disable any serial communication programs running on the workstation (such as synchronization programs).

Open a terminal emulator application (such as HyperTerminal on a PC, or TERM, Tip, or Kermit in a LINUX environment), and configure the application as follows:

In a Windows environment:


Parameter	Value
Bits per second	115200
Data bits	8
Parity	None
Stop bits	1
Flow control	None

Note

Flow control is not supported on the serial consoles when attached to remote terminal servers and must be disabled to ensure proper operation.

In a LINUX environment, enter the following string at the prompt:
```
tip /dev/ttyb -115200
```
If ttyb is already in use, use ttya instead and enter the following string at the prompt:
```
tip /dev/ttya -115200
```
When the terminal emulator application stops reporting information, press Enter. You receive the following login prompt:
```
SLX login:
```

Follow the steps to log into the switch and initial configuration steps in Configuring the Switch for Use.
