Description Definition
● Link Activity ● Blinking green—The link has I/O activity.
2 Host 10Gbase-T iSCSI
Link Speed
● Off—The link is not established, or the link is down.
● Green—The link is up at 10 Gb negotiated speed.
● Amber—The link is up at 1 Gb negotiated speed.
3 OK
● Green—The controller is operating normally.
● Blinking green—System is booting.
● Off—The controller module is not OK, or is powered off.
4 Fault
● Off—The controller is operating normally.
● Amber—A fault has been detected or a service action is required.
● Blinking amber—Hardware-controlled power-up or a cache flush or restore error.
5 OK to remove
● Off—The controller is not prepared for removal.
● Blue—The controller module is prepared for removal.
6 Identify White—The controller module is being identified.
7 Cache status
3
● Green—Cache is dirty (contains unwritten data) and operation is normal. The unwritten
information can be log or debug data that remains in the cache, so a green cache
status LED does not, by itself, indicate that any user data is at risk or that any action is
necessary.
● Off—In a working controller, cache is clean (contains no unwritten data). This is an
occasional condition that occurs while the system is booting.
● Blinking green—A CompactFlash flush or cache self-refresh is in progress, indicating
cache activity.
8 Network Port Activity
Status
4
● Off—The Ethernet link is not established, or the link is down.
● Green—The Ethernet link is up (applies to all negotiated link speeds).
9 Network Port Link Speed
4
● Off—Link is up at 10/100base-T negotiated speeds.
● Amber—Link is up and negotiated at 1000base-T.
10 Expansion Port Status
● Off—The port is empty or the link is down.
● Green—The port is connected and the link is up.
1
10Gbase-T connectors must use qualified cabling options.
2
When powering up and booting, iSCSI LEDs will be on/blinking momentarily, then they will switch to the mode of operation.
3
Cache Status LED supports power on behavior and operational (cache status) behavior.
4
When port is down, both LEDs are off. See also Cache Status LED – power on behavior on page 28.
