you can install the GBI C into Giga Stac k GBIC slot s, a s sh own i n Figur e 2-1.

Install a GigaStack GBIC as follows:

Chapter2 Installation

Step 1 Remove the GigaStack GB IC from its protective packaging .
Step 2 If you want to use t he Giga Stack cable connect or (her eafte r referr ed to as t he

clip), see the “Attaching the GBIC Clip” section on page 2-6.

Step 3 Grip the sides of th e G BIC with your thum b and f ore fin ge r, and insert it int o the

GBIC slot on a switch front pan el, as shown in Figure 2-1, or the
Catalyst 2900 XL 1000BASE-X mod ule sl ot, as sh own in Figu re 2-2.

The GigaStack GBIC is keyed to prevent incorrect insertion.

Step 4 Slide the GigaStack GBIC through the flap cove ring the opening into the slot until

you hear a click. The click means the GigaStack GBIC is locked into the slot.

The GigaStack GBIC software det ects the loop c onfigura tion by the way the
cables are connected and the number of switches used in the stack. The software
uses one of the GigaStack GBIC links as the redundant link, which is disabled for
data transmission while all the other links in the stack are u p. When any other link
in the stack is do wn, t he re du ndant lin k is au to mat ical ly e na ble d f or da ta
transmission. To ensure continued connectivity, the software periodically checks
for changes in the stack and invokes the loop detection algorithm if a new link is
added to the cascade d stack or if a link is remo ved fro m the casca ded stack .

GigaStack GBICs installed in a stack support a loop configuration only if every
Catalyst 2900 XL and 3500 XL switch in the stack is runni ng IOS softwa re
Release 12.0(5) XU or later, Release 12.1( 6)EA2 or late r for Cata lyst 2950
switches, and Release 12 .1(4)E A1 or late r for Catalyst 3550 sw itches.

For Catalyst 2900 XL and 3500 XL switc hes runni ng IOS software e arlier than
Release 12.0(5)XU, an illega l loop is crea ted unde r these co nditi ons:

• A GigaStack GBIC is connected to two other GBIC ports in the same stack.

• A single GigaStack GBIC cable is inserted in port 1 and port 2 of the same

GBIC.

Chapter 2 Installation

Caution A loop causes excessive collision errors on the port and can cause the link to

Removing a GigaStack GBIC

become unstable. This instability decreases performance on the links, and
communication between the switches in the stack is adversely affected.

If a Catalyst switch is connect ed th rou gh its G igaStac k G BIC to an o ther sw itch’s
GigaStack GBI C th at do es n o t s up po r t lo op detection, the GB I C LE Ds tu rn these
colors:

• The GigaStack GBIC LED on the switch without loop detection turns green

almost immediately.

• The GigaStack G BIC LED on the switch with loop detection flashes green for

15 seconds and then tur ns green.
As a result, all GBIC links are enabled if no loop is created. If a loop is

present, the software does not detect it, excessive collisions occur on these
ports, no traffic passes throug h the stack, and the GigaSt ack GBIC LE Ds
remain green.

To avoid problems with loop configurations, make sure that all switches in your
stack are running the a ppropriate IOS release as show n in Table 1-5 on page 1-8.
For more information, see the “Minimum IOS Release fo r Redund ant Loop

Configurations” section on page 1-7. F or switch sof tware upgrade i nforma tion,

refer to the re lea se no tes for y our sw it ch.

Removing a GigaStack GBIC

Remove a GigaStack GBIC as follows:

Step 1 Release the GigaStac k GBIC from t he slot by simulta neously squeezing the t wo

plastic tabs (on e on e ach side of t he GigaSt ack GBIC ).

Step 2 T o remove, slide the GigaStack GBIC out of the slot. A flap drops down to protect

the internal connector.

Warning

Ultimate disposal of this product should be handled according to all national
laws and regulations.

Power-On Self-Test

All supporting switches pe rform a power-on self -test (POST ) on the GigaSt ack
GBIC. When you insert the GigaStack GBIC into the switch or module slot, the
port LED on the switch or modul e turns ambe r while STP ch ecks fo r possible
loops and then t u rns gr ee n. Wh en yo u in ser t a Giga Stac k GBIC c able i nto the
GBIC port, the GigaStack GBIC port turns green if there is network connecti vity;
no additional configur ation is needed . For more info rmati on about the LED
meanings, see the “GigaStack GBIC LEDs” section on page 1-2 and the “GB IC
