Status Indicators

This section discusses the several status indicators, their location, and the meaning of their display status.

Supervisor Module

While the front panel of each switch can house two supervisors, switch operations require only one. Supervisors display switch component status and contain Ethernet management and console ports.

Fabric and Fan-only Module Description displays the supervisor location on each switch.

The supervisor provides one serial console port, two Ethernet management ports, two USB ports, and one clock input port. Supervisor activity is reported by LEDs in the lower left corner. Four LEDs located right of these LEDs report status of other switch components. Figure 1 displays the Supervisor Module.

1 Status LED 5 Fabric module status LED 9 Ethernet management port
2 Active LED 6 Fan module status LED 10 USB ports

Supervisor Activity Status LEDs

Table 1 interprets the states of the Status and Active LEDs.

Table 1. Supervisor Activity LED States
LED Name LED State Supervisor State
Status Off Module failed or is improperly inserted.
Green Supervisor operating normally.
Red Module failed.
Active Off Supervisor is not active.
Green Supervisor is active and controlling the switch.

 

Component Activity Status LEDs

LEDs located below the vents and left of the input ports display summary indicators for power supplies, fabric modules, fan modules, and line cards. Table 2 interprets the states of these indicators. When error conditions are indicated, refer to LEDs on the specified modules to determine the condition’s source.

Table 2. Component Activity LED States
LED Name LED State Module State
Power Supply Line Card Fabric Module Off No modules are present or powered.
Green All powered modules are operating normally.
Red At least one module has failed.
Fan Modules Off Module not inserted.
Amber At least one fan is missing or has failed.
Green All modules are operating normally.
Red There are insufficient functional fans installed in the switch.

Line Card Module Indicators

Each line card module provides one status LED plus LEDs for each port on the card.

The figures in Line Cards indicate the location of the LEDs on each line card. Figure A-2-left displays the status LED and Port LEDs on the left side of the DCS-7300X-64S-LC line card. Figure A-2-right displays the status LED and Port LEDs on the left side of the DCS-7300X-32Q-LC line card.

3 QSFP 1 6 QSFP 4

The Line Card Status LED is in the top left corner of the DCS-7300X Line Card. Table 3 interprets the states of the Status LED.

Table 3. Line Card Status LED States
LED State Status
Off

Line card not inserted.
Green

Line card operating normally.
Yellow

Line card administratively shut down.
Red

Module has failed.

The Line card provides LEDs for each port module socket:

  • Figure 2 displays SFP module LEDs. Each LED corresponds to a module.
  • Figure 3 displays QSFP module LEDs. A set of four LEDs correspond to each module. When the module is programmed as a 40G port, the first LED in the set reports status. When the module is programmed as four 10G ports, each port is assigned to an LED within the set.

Table 4 interprets port LED states.

LED State Status
Off Port link is down.
Green Port link is up.
Yellow Port is disabled in software.

Fan and Fabric Status Indicators

Fan and fabric modules are accessed from the rear panel. Fabric modules are inserted into the switch and fan modules are inserted into the fabric modules.

Each switch contains four fabric modules; the fan module capacity of fabric modules varies by switch model, as displayed in Table 5.

Table 5. Fan Module Capacity
Switch Model Fabric Capacity Switch Capacity
DCS-7304 2 fan modules 8 fan modules
DCS-7308 4 fan modules 16 fan modules
DCS-7316 8 fan modules 32 fan modules

 

Rear Panels displays the rear panel of all switches covered by this guide. Figure 4 displays a DCS-7304-FM fabric module and the fan modules that it contains.

Fan and fabric module indicators are displayed in Figure 4. The fan handle indicates the fan direction. All fan modules must have the same color handle.

Figure 4. Fan Status and Fabric Status LEDs

1 Handle (color indicates airflow orientation) 3 Fan module installation indicator
2 Fabric status LED 4 Fan module status LED

 

The fan module installation indicator is green when the fan module is properly installed or red when the module is not fully installed. Table 6 interprets the states of the Fan and Fabric Status LEDs.

Table 6. Fan and Fabric Status LED States
LED State Status
Off The module is inserted but not receiving power – it may not be properly seated.
Green The module is operating normally.
Red The module has failed.

Power Supply Status Indicators

Power Supply LEDs are on power supply modules. The front panel contains power supply modules for all switches; the DCS-7316 rear panel may also contain power supply modules.

Front Panels (front panels) and Rear Panels (rear panels) displays the position of these LEDs on each switch.

Figure 5 display a power supply module.

The power supply handle indicates the power supply fan direction. Verify the airflow direction of all modules satisfy these criteria:

  • All rear panel modules (fan and power supply modules) have the same color handles.
  • All front panel modules (power supply modules) have the same color handles.

  • Rear panel modules and front panel modules have different color handles.
