NOTE:
The host bus adapter should be SCSI-3 LVDS. A single-ended parallel SCSI host
bus adapter severely degrades performance. Also, if any SE devices are on the same parallel
SCSI bus, all of the devices on the bus slow down to SE speed, which severely degrades
performance.
The library is NOT compatible with a standard differential (Diff) or high-voltage differential
(HVD) SCSI bus.
•
Verify that your HBA is supported by the host computer and qualified with the library. For
current HBA compatibility information, see the BURA Data Agile Compatibility Matrix at
http://
www.hpe.com/info/ebs
.
•
If one of the ports on the device is not connected to another parallel SCSI device, the port
must be terminated. Only the devices physically located at the beginning and end of the
parallel SCSI bus should be terminated. Refer to the manuals supplied with the other devices
on the parallel SCSI bus for information on enabling or disabling termination on those devices.
◦
To terminate the second parallel SCSI port on the device, locate the terminator in the
accessories package and press it firmly into either of the two parallel SCSI connectors
on the back panel. Secure the terminator by tightening the finger-screws until snug. The
supplied terminator is “dual mode” and works on both Low-Voltage Differential (LVD)
and Single Ended (SE) SCSI buses. Check all parallel SCSI and power connections
and confirm that the unit is attached to a valid SCSI SE or LVDS bus.
Operation problems
Table 21 Power problems
Solution
Problem
Device does not power on.
1.
Check all power cord connections.
2.
Make sure the power button on the front panel has been pressed, and the
green
READY
LED is lit.
3.
Make sure the outlet has power. Try another working outlet.
4.
Replace the power cord.
No display messages appear.
1.
Make sure the power cord is connected.
2.
Make sure the power button on the front panel has been pressed, and the
green
READY
LED is lit.
3.
Power cycle the device.
4.
If the display is still blank but the device seems to be powered on, try to
get the device status or error information from the RMI.
All power supply LEDs are off
(MSL4048, MSL8048, and MSL8096).
1.
Check all power cord connections.
2.
Make sure the power button on the front panel has been pressed, and the
green
READY
LED on the front panel is lit.
3.
Make sure the outlet has power. Try another working outlet.
4.
Replace the power cord.
The blue LED is lit when the power supply is plugged into a good outlet. The
green LED is lit when the power supply is producing good power.
1.
Replace the power supply.
Blue power supply LED is lit and
green power supply LED is off
(MSL4048, MSL8048, and MSL8096).
The yellow LED is lit when the power supply fan is not rotating at an acceptable
speed.
Yellow power supply LED is lit
(MSL4048, MSL8048, and MSL8096).
1.
Check the power supply fan for obstructions.
2.
Replace the power supply.
