40 Chapter 3 Powering On/Off Procedure
3.1 AMS200 Rack-Mount Model
The following steps describe power on/off procedures for the AMS200 rack-mount model.
Note: For information about the global rack-mount model, refer to the Acer | HDS AMS200
and WMS100 Global Global 19-Inch Rack Reference Guide.
3.1.1 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 each power unit is turned off.
3. Verify that the circuit breaker (CB1) is turned off.
4. When the RKNAS is mounted on the rack, verify that the AC Power Unit Switch of the
power unit on the RKNAS is turned off.
5. Turn on the circuit breaker (CB1) of the PDB.
6. Turn on the AC Power Unit Switch of the power unit on RKNAS.
7. 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 RKAJ/RKAJAT power unit.
8. Turn on the AC power unit switch of the power unit on RKS.
9. Turn on the main switch.
10. Make sure that the READY LED (green) on the RKS lights within five minutes. When the
RKNAS is connected to the AMS200, make sure that the READY LED (green) on the RKNAS
lights another three minutes later.If the READY LED (green) on the RKS blinks at a high
pace, it blinks for up to 15 minutes because the download of the ENC/SENC firmware is
executed. 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 1: The EALM lamp (red) of the control unit (on the rear side of the subsystem) may
come on between the powering on of the subsystem and entry into the Ready status of the
RKS.
However, it is not a problem if the EALM lamp (red) goes out until the subsystem enters the
Ready status.
Note 2: A NAS system cannot be accessed from a host computer even though the READY LED
of NAS unit illuminates. A NAS system accepts access from a host computer only when of
"ACTIVE" NAS OS Condition.
