Product Overview
Flash Memory Card
Dual-Purpose Port LEDs
The Dual Purpose LEDs show how the port is being used (Ethernet or SFP module). The LED colors have the same
meanings as for the Port Status LEDs, page 9.
PoE Status LED
The PoE STATUS LEDs are located on the front panel, next to the PoE ports (models equipped with PoE ports).The LEDs
display the functionality and status of the adjacent PoE ports.
Flash Memory Card
The switch supports a flash memory card that makes it possible to replace a failed switch without reconfiguring the new
switch. The slot for the flash memory card is on the front of the switch. The flash card is hot swappable and can be
accessed on the front panel in non hazardous locations only. A cover protects the flash card and holds the card firmly in
place. The cover is hinged and closed with a captive screw. This prevents the card from coming loose and protects
against shock and vibration.
Note: For more information on inserting and removing the flash memory card, see Installing or Removing the Flash
Memory Card (Optional), page 16.
Note: The replacement SD card part number is SD-IE-1GB.
Rear Panel
The rear panel of the switch has a latch for installation on a DIN rail. See Figure 5 on page 11. The latch is spring-loaded
to move down to position the switch over a DIN rail and return to the original position to secure the switch to a DIN rail.
Color PoE Status
Off PoE is off. If the powered device is receiving power from a non-PoE power
source, the port LED is off even if the powered device is connected to the switch
port.
Green PoE is on. The port LED is green only when the PoE port is providing power.
Alternating green
and amber
PoE is denied because providing power to the powered device will exceed the
switch power capacity.
Flashing amber PoE is off due to a fault.
Caution: Noncompliant cabling or powered devices can cause a PoE port
fault. Use only standard-compliant cabling to connect Cisco pre-standard
IP Phones and wireless access points or IEEE 802.3af-compliant devices.
You must remove any cable or device that causes a PoE fault.
Amber PoE for the port is disabled. (PoE is enabled by default.)
