Status Indicators

The following topics are covered in this section:

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.

Supervisor Indicators: 7500E-SUP/7500-SUP2

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 upper left corner. Four LEDs located left of the input ports report status of other switch components.

Supervisor Activity Status LEDs

The Status and Active LEDs are located on the left side of the Supervisor Module. Table 1 interprets the states of these two LEDs.

Table 1. Supervisor Activity LED States
LED Name LED State Supervisor State
Status Off No power, failed, or improperly inserted.
Green Operating normally.
Red Supervisor failed.
Active Off Not active.
Green 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, fans, 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 Fans Off No modules are present or powered.
Green All powered modules are operating normally.
Red One or more components failed.

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 4. Line card Status LED
1 Status LED 4 QSFP port 2 LEDs
2 QSFP port 4 LEDs 5 QSFP port 1 LEDs
3 QSFP port 3 LEDs 6 10G / 40G /100G QSFP port LEDs

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 Line card has failed.

The line card provides LEDs for each port module socket:

  • Each LED corresponds to a module.
  • 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 or 100G ports, each port is assigned to an LED within the set.

Table 4 interprets the port LED states.

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

Fabric Status Indicators

Fabric Status LEDs are on fan-fabric modules. Rear Panel display the position of these LEDs on the rear of each switch. Figure 5 display fan status and fabric status LEDs on the switch.

Note: Gen 1 Fabric modules are not supported.

Power Supply Status Indicators

  • PWR-3KT-AC RED
  • PWR-2700-DC-R
  • PWR-3K-DC-RED

The power supply LEDs are on the power supply modules.The position of the LEDs are on the rear of each switch. Figure 7 display all the power supply modules supported on the 7500N.

Figure 7. 7500N Power Supplies

Note: The LEDs for the power supplies with three-LED status indicators are:
  • DC Good
  • Fault, and
  • Vin Good
from top to bottom as shown above.

Table 6 interprets the power supply setup for LED status indicators.
