Enterasys 1000BASE-T Quick Reference Manual

Important Notice
The stacking transceiver must only be installed in the port 25 SFP slot.
Mounting
This switch can be mounted in a standard 19-inch equipment rack or on a
desktop or shelf. Mounting instructions for each type of site follow.
Installing Optional Modules: Before mounting the switch, you may want
to install optional modules. If you have purchased optional slide-in
100BASE-FX, 1000BASE-T, 1000BASE-T/SFP, or stacking modules, install
these modules now, following the instructions in "Installing an SFP
Transceiver."
Rack Mounting
Before rack mounting the switch, pay particular attention to the following
factors:
• Temperature: Since the temperature within a rack assembly may be
higher than the ambient room temperature, check that the rack-
environment temperature is within the specified operating temperature
range: 0°C to 50°C (32°F to 122°F).
• Mechanical Loading: Do not place any equipment on top of a rack-
mounted unit.
• Circuit Overloading: Be sure that the supply circuit to the rack
assembly is not overloaded.
• Grounding: Rack-mounted equipment should be properly grounded.
Particular attention should be given to supply connections other than
direct connections to the mains.
To rack-mount devices:
1. Attach the brackets to the device using the screws provided in the
Bracket Mounting Kit.

3. If installing a single switch only, turn "Connecting to a Power Source."
4. If installing multiple switches, mount them in the rack, one below the
other, in any order.
Desktop or Shelf Mounting
1. Attach the four adhesive feet to the bottom of the first switch.
2. Set the device on a flat surface near an AC power source, making sure
there are at least two inches of space on all sides for proper air flow.
3. If installing a single switch only, refer to "Connecting to a Power
Source."
4. If installing multiple switches, attach four adhesive feet to each one.
Place each device squarely on top of the one below, in any order.
Installing an SFP Transceiver
To install an SFP transceiver, perform the following steps:
1. Consider your network and cabling requirements to select an
appropriate SFP transceiver type.
2. Insert the transceiver with the optical connector facing outward and the
port connector facing down. Note that SFP transceivers are keyed so
they can only be installed in one orientation.
3. Slide the SFP transceiver into the port until it clicks into place.
Note: SFP transceivers are hot-swappable. The switch does not need to be powered
off before installing or removing a transceiver. However, always first disconnect the
network cable before removing a transceiver.
Installing a Stacking Transceiver
The stacking transceiver must be installed in the port 25 slot. It should be
inserted before any of the systems in the stack are powered on.
Slide the SFP transceiver into the SFP transceiver slot until it clicks into
place. To remove, pull on the tab at the bottom of the front of the
transceiver.
Connecting Switches in a Stack
Note: The stacking transceiver must only be installed in the port 25 SFP slot.
To connect up to eight switches in a stack, perform the following steps:
1. Install SFP stacking transceivers into the port 25 slot for each switch in
the stack.
2. Plug one end of a stack cable into the Tx (top) port of the top unit.
3. Plug the other end of the stack cable into the Rx (bottom) port of the
next unit.
4. Repeat steps 1 and 2 for each unit in the stack. Form a simple chain
starting at the Tx port on the top unit and ending at the Rx port on the
bottom unit (stacking up to eight units).
5. Complete the stack connections by plugging one end of a stack cable
into the Tx port on the bottom unit and the other end into the Rx port
on the top unit.
6. Select the Master unit in the stack by pressing the Master button in on
only one of the switches. Only one switch in the stack can operate as the
Master, all other units operate in slave mode. If more than one switch in
the stack is selected as Master, or if no switches are selected, the stack
will not function.
Note: The stacking feature requires that all stacking transceiver ports be connected
and the switches powered on. If one stack link is not connected, or if a switch is
powered off, the stack will not function.
Connecting to a Power Source
To connect a switch to a power source:
1. Insert the power cable plug directly into the AC receptacle located at
the back of the switch.
2. Plug the other end of the cable into a grounded, 3-pin socket, AC power
source.
Note: For International use, you may need to change the AC line cord. You must use
a line cord set that has been approved for the receptacle type in your country.
3. Check the front-panel LEDs as the device is powered on to be sure the
PWR LED is lit. If not, check that the power cable is correctly plugged
in.
4. If you have purchased a Redundant Power Unit, connect it to the switch
and to an AC power source now, following the instructions included
with the package.
Port and System Status LEDs
The V2H124-24P base unit also includes a display panel for key
system and port indications that simplify installation and network
troubleshooting. The LEDs, which are located on the front panel for
easy viewing, are shown below and described in the following tables.
Use the Mode PoE/Link button on the front panel to toggle between the
two display modes as described in the following table. The current mode
is indicated by the Link/Act and PoE system LEDs.
