Installing A Gbic Transceiver - Alcatel OS-6124 Getting Started Manual

OmniStack 6124
®
Note the following points about a closed-loop stack:
• The OS-6100-RST-KIT Redundant Stacking Module must be installed in the unit
that contains the master Management Module (Unit ID = 1). All other switches in
the stack can use the OS-6STK-KIT Stacking Module.
• To form a closed loop, connect the 1 m long stacking cable (included in the
Redundant Stacking Module kit) from the Up port on the top switch to the Down port
on the bottom switch.
• To enable the closed-loop function, be sure that the button on the panel of the
Redundant Stacking Module is fully pressed in. Use the tip of a pen or other sharp
object to achieve this.
Note: Do not leave one end of a stacking cable unconnected. Be sure both ends are
properly connected, or remove the cable entirely.

Installing a GBIC Transceiver

The lower two slots on the rear panel can be
used for a single-port GBIC uplink module.
This module supports 1000BASE-SX, 1000BASE-LX and 1000BASE-LH 5 V GBIC
transceivers.
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 220 m (722 ft) away with 62.5/125 micron multimode fiber
cable, or up to 500 m (1641 ft) with 50/125 micron 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 5 km (16404 ft) away with single-mode fiber
cable.
The 1000BASE-LH GBIC transceivers provide one long-wavelength (1550 nm)
Gigabit port that can be used for a long-haul connection to a remote site. This port can
be connected to a site up to 70 km (43.5 miles) away with single-mode fiber cable.
Caution: Install only 5 V GBIC transceivers into the module slots.
You can install a GBIC transceiver as described below:
1. Insert the tranceiver with the SC connector facing out toward you. Note that the
transceiver is keyed so that it can only be installed in one orientation.
2. Press in on the transceiver's side tabs, and gently slide it into the GBIC
interface slot until it clicks into place.
Notes: 1. GBIC transceivers are hot-swappable. You do not need to power off the
switch before installing or removing a transceiver.
2. For 64-byte frames, the GBIC module is known to drop a certain percentage
of traffic.
