The node interconnect switch is a 1U switch chassis that contains interconnect and management components, including two interconnect switches, the service processor (SVP), an ethernet switch (SSVP), the operation panel, and two power supplies with a built-in cooling fan. The primary and secondary node interconnect switches must be installed in the storage system. For the secondary node interconnect switch, the SVP and SSVP are optional.



Identifier Name Description
1 Operation Panel The operation panel shows system status with LED and controls power on and off of the storage system.
2 Backup Service Processor A redundant SVP in case the main SVP fails.
3 Main Service Processor The SVP provides status information about the storage system.
4 Ethernet Switch (SSVP) The SSVP is a LAN hub that connects the SVP to each controller chassis, optional SSVP, and maintenance PC.


Number Item Description
1 REMOTE MAINTENANCE ENABLE/DISABLE

Used to enable or disable the remote maintenance of the storage system.

ENABLE: Remote maintenance is allowed.

DISABLE: Remote maintenance is not allowed.

2 PS SW ENABLE

Move this switch to the ENABLE position to allow the PS ON/PS OFF switch to power on or power off the storage system.

3 PS ON/PS OFF

To power on or off the storage system, move this switch while holding the PS SW ENABLE switch in the ENABLE position.

4 LOCATE

Amber: The node interconnect switch needs maintenance.

Off: Normal condition.

5 READY

Green: I/O operation on the channel interface is possible.

Off: Not ready.

6 ALARM

Red: The storage system is down, or an MP block occurred.

Off: Not in the alarm status.

7 MESSAGE

Amber: The storage system is down, or an MP block occurred. The storage system detected a failure, and a SIM related to the failure was reported to the SVP. The LED continues to light until the maintenance personnel changes the SIM attribute to 'complete'.

One blinking amber: SVP became faulty in a single SVP configuration.

Two blinking amber: SVPs became faulty in a dual SVP configuration. If one of the two SVPs becomes faulty in a dual SVP configuration, this LED does not blink.

8 REMOTE MAINTENANCE PROCESSING

Amber: Remote maintenance (ASSIST) is being operated.
