Instruction Manual

StatusDescriptionItem
Off = The EPS/RPS is not connected or is not powered.
Green = The cooling fan is working properly.Fan status LED6
Off = One of the unit’s fans has failed. The switch Fault LED will be blinking
simultaneously.
Green = The switch self test and initialization are in progress after the switch has
been power cycled or reset. The switch is not operational until this LED goes off.
Self test LED6
Blinking green
1
= A component of the switch has failed its self-test. The status LED
for that component and the switch Fault LED will blink simultaneously.
Off = The switch is not undergoing self test.
Press the button to step from one mode to the next. The current mode setting is
indicated by the Mode select LEDs near the button.
Mode select button7
Link = Indicates that the port LEDs are displaying link information. If the port LED
is on, the port is enabled and receiving a link indication from the connected device.
Mode select LEDs8
If the port LED is off, the port has no active network cable connected, or is not
receiving link beat or sufficient light. Otherwise, the port may have been disabled
through the switch console, the Web browser interface. If the port LED is blinking
1 simultaneously with the Fault LED, the corresponding port has failed its self-test.
Act = Indicates that the port LEDs are displaying network activity information.
FDx = Indicates that the port LEDs are lit for ports that are in full-duplex mode. Off
indicates half duplex.
Spd = Indicates that the port LEDs are displaying the connection speed at which
each port is operating. If the port LED is off, the port is operating at 10 Mb/s. If
the port LED is flashing2, the port is operating at 100 Mb/s, and if the port LED
is on continuously, the port is operating at 1000 Mb/s.
Displays port link information, network activity information, whether the port is
configured for full-duplex operation, or the speed of the connection, depending
on the LED Mode selected.

• If the Link (Lnk) indicator LED is lit, each port LED displays link information for
the associated port. If the port LED is in Link mode and it is blinking, the port
has failed its self test. The Fault and Self-Test LEDs will be blinking simultaneously.
• If the Activity (Act) indicator LED is lit, each port LED displays activity information
for the associated port — it flickers as network traffic is received and transmitted
through the port.
• If the Full Duplex (FDx) indicator LED is lit, the port LEDs light for those ports that
are operating in full duplex mode.
• If the Speed (Spd) indicator LED is lit, the port LEDs behave as follows to indicate
the connection speed for the port:
◦ OFF = 10 Mb/s
◦ Flashing = 100 Mb/s (the flashing behavior is a repeated on/off cycle once
every 0.5 sec.)
◦ ON = 1000 Mb/s
For the dual-personality ports (ports 21 through 24), indicates which connector is
enabled:
T/M LEDs10
• T = Indicates the 10/100/1000Base-T RJ-45 port is enabled.
• M = Indicates the mini-GBIC port is enabled.
