Indicator/Button

Color and Status

Description

System status indicator

Off

The system is not running.

Green

  • Fast blinking: The system is starting.
  • Slow blinking: The system is operating properly.

Steady red

  • The device is incorrectly started.
  • An alarm is generated on a PSU.
  • An alarm is generated on a fan module.

Stack master/slave indicator

Off

The switch is not the stack master switch.

Steady green

The switch is the stack master switch or a standalone switch.

STAT indicator

Off

The STAT mode is not selected.

Steady green

The STAT mode (default mode) is selected, and service port indicators show the link connection states and link activity on ports.

SPEED indicator

Off

The SPEED mode is not selected.

Steady green

The SPEED mode is selected, and service port indicators show the speed of each port.

STACK indicator

Off

The STACK mode is not selected.

Steady green

The STACK mode is selected, and service port indicators show the stack member ID or leaf ID of the local switch.

MODE/ID: mode switch button and ID indicator

NOTE:

The mode switch button on the rear panel is integrated with the ID indicator. There is only an ID indicator and no mode switch button on the front panel.

Mode switch button: -

  • When you press the MODE button once, the SPEED indicator turns green and service port indicators show the speed of each port.
  • When you press the MODE button a second time, the STACK indicator turns green and service port indicators show the stack member ID of the local switch.
  • When you press the button a third time, the STAT indicator turns green (default mode) and service port indicators show the link connection states and link activity on ports.

If you do not press the MODE button within 45 seconds, the service port indicators restore to the default mode. In this case, the STAT indicator is steady green, the SPEED and STACK indicators are off.

ID indicator: Off

The ID indicator is not used (default state).

ID indicator: steady blue

The device is remotely located by O&M personnel.

Service port indicator (GE electrical port)

NOTE:

The indicator on the left indicates the port at the top, and the indicator on the right indicates the port at the bottom.

The meaning of the service port indicators varies according to the current mode. For details, see Table A-55.

Service port indicator (10GE optical port)

NOTE:

Each 10GE optical port has two single-color indicators. The one on the left is the ACT indicator (yellow), and the one on the right is the LINK indicator (green).

Arrowheads show the positions of ports. A down arrowhead indicates a port at the bottom, and an up arrowhead indicates a port at the top.

The meaning of the service port indicators varies according to the current mode. For details, see Table A-55.

Service port indicator (40GE optical port)

NOTE:

Arrowheads show the positions of ports. A down arrowhead indicates a port at the bottom, and an up arrowhead indicates a port at the top.

The meaning of the service port indicators varies according to the current mode. For details, see Table A-55.

When a 40GE port is divided into four 10GE ports, this indicator shows the status of a 10GE port. The sequence number of the indicated port is identified by the 10GE mode sequence number indicators of the 40GE port (1, 2, 3, or 4) on the lower right corner of the panel.

NOTE:

Each 40GE port has a single-color indicator, which shows the status of the 40GE port by default.

If a 40GE port is not split and is connected to four 10GE ports on a remote device using a one-to-four high-speed cable, the 40GE port cannot go Up and its indicator is off.

40GE Breakout 1/2/3/4 (sequence number indicators of 10GE ports converted from a 40GE port)

NOTE:

Indicators 1, 2, 3, and 4 are turned on in cyclic order, with each indicator keeping on for 5 seconds.

Off

40GE ports are working in 40GE mode and not divided into four 10GE ports.

Green

At least one 40GE port works in 10GE mode and is split into four 10GE ports.

When a 40GE port is divided into four 10GE ports, these indicators identify the sequence numbers of the 10GE ports together with the service port indicator (40GE optical port). A port indicator (8 in Figure A-66) shows the status of a 10GE port converted from the corresponding 40GE port:

  • When indicator 1 is on, each port indicator shows the status of the first 10GE port derived from the corresponding 40GE port.
  • When indicator 2 is on, each port indicator shows the status of the second 10GE port derived from the corresponding 40GE port.
  • When indicator 3 is on, each port indicator shows the status of the third 10GE port derived from the corresponding 40GE port.
  • When indicator 4 is on, each port indicator shows the status of the fourth 10GE port derived from the corresponding 40GE port.

USB-based deployment indicator

Off

USB-based deployment is disabled by default.

Green

  • Steady on: USB-based deployment has been completed.
  • Blinking: The data on the USB flash drive is being read.

Steady red

USB-based deployment has failed.

Green

  • Steady on: The link is normal.
  • Blinking: The port is receiving or sending data.
