3.2 AMS200 Floor Model

The following steps describe power on/off procedures for the AMS200 floor model.

3.2.1 Subsystem Power On

Note: The EALM lamp (red) of the controller (on the rear side of the subsystem) may come

on between subsystem power-on and Ready status. However, it is not a problem if the EALM

lamp (red) goes out during this period of time.

To power on the subsystem:

1. Verify that the main switch is turned off.

2. Verify that the AC power unit switch of the power unit is turned off.

3. Turn on the AC Power Unit Switch of the power unit on RKAJ/RKAJAT.

Note: When two or more disk drives are not installed on the additional disk drive unit side,

shut off the power to the power unit (RKAJ).

4. Turn on the AC Power Unit Switch of the power unit on RKS.

5. Turn on the main switch.

6. Verify that the READY LED (green) lights within five minutes. If the READY LED (green)

blinks rapidly, the ENC firmware is downloaded. Even when the READY LED (green) blinks,

the subsystem is operational. If the ALARM LED (red) or WARNING LED (orange) lights,

refer to section 8.1.

Note: The EALM lamp (red) of the control unit (on the rear side of the subsystem) may come

on between subsystem power-up and entry into the Ready status. However, it is not a

problem if the EALM lamp (red) goes out until the subsystem enters the Ready status.
