Overview
: The SM8TAT2SA-DC managed GbE PoE+ switch offers powerful L2 features with better functionality and
usability. It delivers 8 (10M/100M/1G) RJ45 with 8 PoE+ (supports 802.3 at/af and total up to 130W) ports and 2 GbE SFP
ports. This DC-powered switch provides a cost-effective solution for power and data connectivity in a Service provider
environment with 48-54 VDC input.
System LED
:
Indicates if the switch is powered up correctly or if a system alarm is triggered.
Mode LEDs
:
Indicate the mode of all switch ports. Press the
Mode/Reset
button sequentially
to switch between Link/Activity/Speed mode and PoE mode.
Port Status LEDs
:
Indicate the current status of each port in different modes after changing the
mode by pressing
Mode/Reset
button. Press the
Mode/Reset
button for less than 2 seconds to change LED modes
(Link/Act/Speed Mode or PoE Mode).
Mode/Reset button
:
Change LED Mode
: press for 0 ~ 2 seconds; the SYS LED is lit green; Port LED status changes
based on the mode selected.
Reset Switch
: press for 2 ~ 7 seconds; the SYS LED blinks green; Port LEDs are all Off.
Restore to Defaults
: press for 7 ~ 12 seconds; the SYS LED blinks green; Port LEDs are all On.
Once the LED behaviors are correctly displayed, release the button. Press the
Mode/Reset
button until all port LEDs
light, then release the
Mode/Reset
button. This sets the switch back to its factory default IP address; log back in to
display the First Time Wizard.
Package Contents
:
Verify that the box contains one Switch, two Rack Mount brackets, four rubber feet, one this
manual, and one documentation postcard.
19’’Rack Mounting
:
1.
Attach the mounting brackets to both sides of the chassis. Insert screws and tighten then
with a screwdriver to secure the brackets.
2.
Place the switch in the rack. Align the oval holes in the brackets with
the mounting holes in the rack posts.
3.
Attach the brackets to the posts. Insert screws and tighten them.
Wall Mounting
:
1
. Install user-supplied screws on the appropriate location on the wall and note the dimensional
limitation of the screws.
2
. Make sure that the switch is attached securely to wall.
Desk or Shelf Mounting
:
1
. Verify the workbench is sturdy and reliably grounded.
2
. Attach the four adhesive-
backed rubber feet to the bottom of the switch.
Grounding
:
After the switch is mounted and connected, the back panel grounding
screw can be used for grounding. Grounding and wire routing help limit the effects of
noise due to electromagnetic interference (EMI). Run the ground connection from the
ground screw to the grounding surface before connecting devices.
ATTENTION
: This SM8TAT2SA-DC case must be earth grounded for correct operation of
internal transient protection circuitry.
See the Install Guide for important Cautions and Warnings regarding Switch
and Power Supply grounding
. Neither DC input polarity may be earth grounded. If DC power distribution bus has one
side tied to earth ground, then use of an isolated DC-DC power Supply between the DC power distribution bus and
SM8TAT2SA-DC is required to ensure that the PoE ports are isolated from earth ground as required by the
IEEE802.3af/at/bt specification.
