SRUX5

SRUX5

Card Overview

A Service and Router Unit (SRU) integrates the control and management functions and provides the control plane, management plane, and switching plane for the system.
  • Control plane: provides functions such as protocol processing, service processing, route calculation, forwarding control, service scheduling, traffic statistics collection, and system security.
  • Management plane: provides functions such as system monitoring, environment monitoring, log and alarm processing, system software loading, and system upgrade.
  • Switching plane: provides high-speed, non-blocking data channels for service switching between service modules.

SYS

Green

Slow blinking: The system is running properly.

Fast blinking: The system is being powered on or restarting.

Red

Steady on: A fault that affects services has occurred and cannot be rectified automatically. The fault needs to be rectified manually.

Off

The system software is not running or is resetting.

2

ACT (active/standby status indicator)

Green

Steady on: The SRU is in active state.

Off: The SRU is in standby state.

3 and 4
GE electrical interface indicators:
  • 4: LINK indicator, green
  • 3: ACT indicator, yellow

Green

LINK indicator steady on: A link has been established on the interface.

LINK indicator off: No link is established on the interface.

Yellow

ACT indicator blinking: Data is being transmitted or received on the interface.

ACT indicator off: No data is being transmitted or received on the interface.

5

ACT (USB)

Red and green

Steady green: The system has been upgraded or configured using a USB flash drive.

Blinking green: The system is being upgraded or configured using a USB flash drive.

Steady red: The system fails to be upgraded or configured using a USB flash drive.

Off: No USB flash drive is connected, the USB interface has failed, or the indicator has failed.

6

CON/AUX EN

NOTE:
  • The CON/AUX interface and the Mini USB interface are multiplexed, and only either of them can be used at a time.
  • By default, the CON/AUX interface is effective and the EN indicator is steady green, regardless of whether a cable is connected to the interface.

Green

Steady on: The CON/AUX interface is enabled.

Off: The CON/AUX interface is disabled.

7

Mini USB EN

Green

Steady on: The Mini USB interface is enabled.

Off: The Mini USB interface is disabled.

8

OFL

Blue

Steady on: The OFL button has been held down for more than 4s, and the hard disk can be removed.

Off: The hard disk cannot be removed.

NOTE:

The OFL indicator only shows whether the hard disk can be removed while the power is on. It cannot identify service status in the hard disk.

9

RST button
NOTICE:

This button is used to reset the SRU manually. Resetting the SRU will cause service interruption. Exercise caution when using this button.

10

Hard disk error indicator

Red

Steady on: The hard disk does not work normally.

Off: The hard disk is working normally.

11

Hard disk ACT indicator

Green

Steady on: A hard disk is present.

Blinking: The system is performing read-write operation on the hard disk.

Off: No hard disk is present.

NOTE:

This indicator keeps blinking during hard disk formatting after the formatting command is executed.
