VERTICAL HORIZON
GIGABIT ETHERNET
CONVERTER MODULE (GBIC)
Enterasys Networks VHIM1000-S1GM Gigabit
Ethernet Converter Module provides one slot for a
fiber-optic GBIC transceiver. Enterasys currently sells
the following transceivers:
•1000Base-SX
(Aglient HFBR5601 or Finisar FTR-8519P)
•1000Base-LX
(Aglient HFCT5611)
The 1000Base-SX GBIC transceivers provide one
short-wavelength (850 nm) Gigabit port that can be
used for a high-speed backbone or server connection.
This port can be connected to a site up to 550 m (1805
ft) away with multimode fiber cable.
The 1000Base-LX GBIC transceivers provide one
long-wavelength (1300 nm) Gigabit port that can be
used for a high-speed backbone or server connection.
This port can be connected to a site up to 10 km
(6.21 miles) away with single-mode fiber cable.
Gigabit Port LEDs
Port LEDs for the module are located on the front
panel of the switch. These LEDs provide port status for
“at-a-glance”network monitoring. The following table
details the indicator functions provided by the Vertical
Horizon switch:

INSTALLING THE MODULE
CAUTION: This module is designed to be used with
the Vertical Horizon Series products only. Do not try to
install this module in any other units.
Be sure to install the VHIM1000-S1GM GBIC module
into the appropriate slot on the switch. Refer to the
product User Guide for detailed information.
Equipment Checklist
After unpacking the VHIM1000-S1GM module, check
the contents of the box to be sure you’ve received the
following items:
•One VHIM1000-S1GM module
•This document
Handling the Module
CAUTION: The VHIM1000-S1GM module can easily
be damaged by electrostatic discharge.
To prevent electrostatic damage, observe the following
guidelines:
•Do not remove the module from its packaging until
you are ready to install it.
•Do not touch any of the module’s pins, connectors
or components.
•Hold the module only by its edges or front panel.
•Wear an anti-static wristband connected to a
suitable earth ground whenever handling the
module.
•Store or transport this module only in appropriate
anti-static packaging.
Instructions
CAUTION: The switch must be powered off before
installing or replacing any module.
1. Power off the switch: Disconnect the AC power
cord from the switch. If a redundant power unit
(RPU) is present, disconnect its DC cable
connection to the switch.
2. Remove network cables: If you are replacing a
module, remove the cable attached to the port on
the module.
3. Loosen the screws on the installed module or
slot faceplate: Using your fingers or a flathead
screwdriver, turn the screws securing the module
(or faceplate on the slot) in a counter-clockwise
direction until they are free of the chassis. Be sure
not to completely remove the screws from the
module or faceplate.
4. Remove the installed module or faceplate:
Firmly pull on the screws until the module is free of
the switch. Carefully slide the module straight out of
the slot.
Keep the original faceplate for future use. If you
should remove the module, replace the faceplate to
prevent dust and debris from entering the unit and
to maintain proper air flow.
5. Insert the new module into the switch: Holding
the new module with the text on the front panel
upright, carefully slide the module into the switch
slot and press gently until it snaps into place. Be
sure the new module’s front panel is flush with the
switch panel.
6. Secure the new module: Secure the new module
in place by screwing the attached screws clockwise
into the switch’s chassis. Tighten them enough to
secure the module, but not so tight as to prevent
them from being unscrewed by hand.
7. Insert the GBIC transceiver: Insert the tranceiver
with the SC connector facing out toward you. Press
in on the transceiver’s side tabs, and gently slide it
into the GBIC interface slot until it clicks into place.
Note that the transceiver is keyed so that it can
only be installed in one orientation.
8. Connect the network cable: Connect fiber cable
to the SC-type port on the GBIC transceiver. See
“Connectivity Guidelines”in this guide for further
information.
9. Power on the switch: Reconnect the previously
removed power sources to the switch. The switch’s
front-panel LEDs should indicate the status of the
new connection. Check the LED indicators for the
fiber port on the GBIC transceiver to ensure that
they are operating correctly. Refer to the table of
LEDs in this guide for a description of the LED
indications. If the module does not respond, see
“Troubleshooting”below.
Note: If you need to replace a GBIC transceiver,
remove it from the slot by pressing in on the
side tabs, and gently sliding the transceiver out.
More details concerning connection options and
network applications can be found in the product’s
User Guide. Information on the module’s configuration
options can be found in the Management Guide that is
included with the base unit.
TROUBLESHOOTING
If you experience any problems with the module, check
the following items before contacting Enterasys
Technical Support:
•Ensure the switch with the GBIC converter module
and installed GBIC transceiver is powered up.
•Ensure that the device attached to the GBIC
transceiver is powered up and operating correctly.
•Ensure that the GBIC converter module is properly
seated in the interface slot on the switch, and that
the GBIC transceiver is properly inserted in the
module.
•Verify that the attached device is configured to
match the communication mode used by the
transceiver (1 Gbps, and half or full duplex).
•Check the connectors on both ends of the cable to
be sure they are properly engaged. When attaching
fiber cable to an SC-type port, be sure the plug
clicks into place to ensure that it is properly seated.
•Be sure the fiber terminators are clean. You can
clean the cable plugs by wiping them gently with a
clean tissue or cotton ball moistened with a little
ethanol. Dirty fiber terminators on fiber optic cables
will impair the quality of the light transmitted through
the cable.
