LightStream 2020 Upgrade to Dual Power Cords 9

Upgrading Disk Assemblies

Step 16 Switch the power on each power tray to on. The system should resume normal operation

on its own. If it does not, or if you observe one of the indicators listed below, contact Cisco’s

Technical Assistance Center (TAC) at 800 553-2447, 408 526-7209, or [email protected].

• Look for a green LED behind the grille on each new power tray. If the LED is not lit

when power is turned on, there may be a fault in the power tray.

• If one or both NPs does not come up, there may be a fault in a new disk assembly.
