Lan Connector Lamps; Link/Act Lamps; Speed Lamp - NEC Express5800/120Rf-2 User Manual

Note:
configuration (RAID1, RAID5, or RAID0+1), the server can
continue operation. However, replace the disk as soon as
possible, and perform reconstruction (rebuild) processing.
(The failing disk can be replaced in hot swap mode.)
!
Flashing switching back and forth between green and amber indicates
that reconstruction (rebuild) processing is being performed for the hard
disk. (This flashing does not indicate a failure.) When a failing hard disk
is replaced in disk array configuration, the system automatically rebuilds
the data. (Auto-rebuild function) The lamp switches back and forth
between green and amber during rebuild processing.
The lamp goes off when the rebuild processing has terminated. It turns
amber when the rebuild processing fails.
Note:
processing, the processing is stopped. Restart the server,
mount the new hard disk in hot swap mode, and then
perform the rebuild processing again. Observe the following
notes on using the auto-rebuild function:
Do not turn the power off. (Once the power is turned off, the
auto-build function does not start.)
Let 90 seconds or more pass between dismounting a failing
hard disk and when mounting a new one.
Do not replace a failing hard disk while rebuild processing is
being performed for another hard disk

LAN Connector Lamps

There are two lamps for each of the two LAN ports (connectors) on the rear
panel. See Figure 2-37, Q, R, T, and V for the locations of the LAN connector
lamps.

LINK/ACT Lamps

Each LINK/ACT lamp indicates the status of the standard network port of the
server. While power is supplied to the server and HUB and the connection is
correct, the lamp is on green. (LINK) The lamp turns green and flashes while
the network port is transmitting/receiving data. (ACT)

Speed lamp

This lamp indicates whether the network port is operating through a 1000BASE-
T, 100BASE-TX or 10BASE-T network interface. If the lamp is lit amber, the
network port is operating through 1000BASE-T. If the lamp is lit green, the
network port is operating through 100BASE-TX. If the lamp is off, the network
port is operating through 10BASE-T.
