Removing SFP+ Modules
1. Attach an ESD-preventive wrist strap to your wrist and to a bare metal surface.
2. Disconnect the cable from the SFP+ module. For reattachment, note which cable connector plug is send (TX)
and which is receive (RX).
3. Insert a dust plug into the optical ports of the SFP+ module to keep the optical interfaces clean.
4. If the module has a bale-clasp latch, pull the bale out and down to eject the module. If the latch is obstructed
and you cannot use your finger, use a small, flat blade screwdriver or other long, narrow instrument to open
the latch.
5. Grasp the SFP+ module and carefully remove it from the module slot.
6. Place the module in an antistatic bag or other protective environment.
DIP Switch Settings
The front panel 4-Position DIP Switch (SW1) is shown and described below. The figure below shows SW1 default
settings.
The factory default setting is DIPs 1-4 set to (UP=1=OPEN=Left=default setting).
DIP #
Description
Position (Up = 1, Down =0)
1
Enable/Disable PHO
to PoE-Power
interlock.
1
= PHO (PoE Hardware Override) function is Disabled (default).
0
= PHO Enabled. PHO provides a turn-off of the PoE power delivery in the
event of an external trigger.
Note
that enabling the PHO function using DIP
switch #1 dedicates both DIO interfaces to the PHO function. The CPU then
no longer has any control over the DIOs; the CPU can then only monitor the
status of the DIO/PHO function.
Note
: Do not enable until this feature is fully
supported. (PHO is currently Disabled by default; do not override until fully
supported.)

Input 1 relay normal
state (not active)
1
= Relay is normally open (default).
0
= Relay is normally closed.
3 and 4 PoE power down
selection
11
= Power down all TP ports. (default).
10
= Power down just TP Ports 1-4.
01
= Power down just TP Ports 5-8.
00
= Power down just Expansion slots (not currently used)
