Briefly press the
SW0
switch to silence the audible alarm. This can also be done via the graphical
user interface (GUI) (see the
Nexsan RAID Storage User Guide
).
Press and hold the
SW0
switch for approximately 8 seconds to power down the RAID Controllers. If
there is data in the cache, it will be stored in flash memory. This is the same as performing a System
Shutdown via the graphical user interface (GUI) (see the
Nexsan RAID Storage User Guide
). On dual-
controller systems, both
SW0
switches must be held simultaneously for 8 seconds.
With the unit powered off:
Press and hold the
SW0
switch on either RAID Controller for approximately 4 seconds to power up
the unit. Release the
SW0
switch to boot normally.
Continue pressing the
SW0
switch after the unit powers up to put the RAID Controllers into
Emergency mode (see the
Nexsan RAID Storage User Guide
). Emergency mode is indicated by the
controller status LED alternating between blue and red (see
LEDs
on page 6).
Turbo cards (VT units only)
17. Turbo card LEDs: The LEDs on the turbo card indicate the status of the card. The LEDs are:
SP
: Currently unused.
PAR
: Indicates the status of the parity engine. Green indicates that the parity engine is active. If the
parity engine is inactive, this LED is off.
MEM
: Indicates the status of the turbo card’s cache memory. Green indicates that data is in the
cache that needs to be written to disk. If there is no data in the cache, this LED is off.
STAT
: Indicates the status of the turbo card. Green indicates that the card is operating normally.
Orange indicates that the card is initializing its cache memory. Red indicates a fault in the turbo card.
If the turbo card has been deactivated, this LED is off.
Host port options
Figure 1-5: Host port options
Fibre Channel
10gb Ethernet, Optical
10gb Ethernet, Copper
SAS-to-Host
The RAID Controllers can be configured (with one or two optional Host Bus Adapter (HBA) cards) for one of
four different host port options: 16Gb/s Fibre Channel, 8Gb/s Fibre Channel, 10Gb/s iSCSI (10GbE), or SAS-
to-Host.
Note
Because of the presence of the turbo card (see
Turbo cards (VT units only)
above), Nexsan E60VT™
and Nexsan E48VT™ units can only have one HBA card installed.
1. Depending on the RAID Controller configuration, the host port connectors are one of the following:
Two Fibre Channel ports (
0
and
1
) per HBA card: 16Gb/s or 8Gb/s Fibre Channel optical SFPs.
Two 10Gb iSCSI (10GbE) ports (
0
and
1
) per HBA card: 10Gb/s Ethernet optical SFPs or copper SFP
sockets for iSCSI.
Two SAS ports (
0
and
1
) per HBA card: Mini-SAS 26 pin I-Pass (8088) connectors, each with four
6GB/s SAS links.
