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. |

|---|---|---|
| 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. |
