Overview  
The GigaStack GBIC (model WS-X3500-XL) adds port density and  
high-performance connectivity to supporting switches. When installed in a  
supporting switch, the GigaStack GBIC supports Gigabit connections in a  
cascaded stack or point-to-point configuration. The GigaStack GBIC  
autonegotiates the duplex setting of each port to maximize the bandwidth for your  
configuration.  
Features  
This section describes the GigaStack GBIC features:  
Half-duplex stacking using only one GBIC slot for each switch  
Stack up to nine switches to form an independent backbone that can be  
managed with a single IP address. This stack gives the appearance of a single  
large switch for network management purposes. For this kind of connectivity,  
see the Example 1: Cascaded Stack Connectionsection on page 1-9.  
Full-duplex connectivity between two switches  
You can also form a point-to-point link between two switches. The GigaStack  
GBIC supports one full-duplex link (in a point-to-point configuration) or up  
to eight half-duplex links (in a stack configuration) to other Gigabit Ethernet  
devices. For this kind of connectivity, see the Example 2: Point-to-Point  
Connectionsection on page 1-10.

Avoiding Electrostatic Discharge  
Avoiding Electrostatic Discharge  
Before you install the GigaStack GBIC, ground yourself by touching the metal  
part of the chassis to avoid electrostatic discharge (ESD). You should also keep  
the GigaStack GBIC in its antistatic shielded bag until you are ready for  
installation.  
Installing a GigaStack GBIC  
Gigabit Ethernet switches are shipped without the GigaStack GBIC. However,  
you can install the GBIC into GigaStack GBIC slots, as shown in Figure 2-1.  
Install a GigaStack GBIC as follows:  
Step 1  
Step 2  
Remove the GigaStack GBIC from its protective packaging.  
If you want to use the GigaStack cable connector (hereafter referred to as the  
clip), see the Attaching the GBIC Clipsection on page 2-6.  
Step 3  
Grip the sides of the GBIC with your thumb and forefinger, and insert it into the  
GBIC slot on a switch front panel, as shown in Figure 2-1, or the  
Catalyst 2900 XL 1000BASE-X module slot, as shown in Figure 2-2.  
The GigaStack GBIC is keyed to prevent incorrect insertion.  
Step 4  
Slide the GigaStack GBIC through the flap covering the opening into the slot until  
you hear a click. The click means the GigaStack GBIC is locked into the slot.

Attaching the GBIC Clip  
Each GigaStack GBIC ships with a removable clip that can be attached to provide  
extra security against accidental cable removal. If you use the clip, you must  
attach it before inserting the GBIC into the slot.  
Attach the clip as follows:  
Step 1  
Attach the clip to the GBIC by carefully inserting the clip tabs into the slots on  
either side of the GBIC, in the orientation shown in Figure 2-3. Slide the clip  
toward the port side of the GBIC.

The GigaStack GBIC software detects the loop configuration 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 up. When any other link  
in the stack is down, the redundant link is automatically enabled for data  
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 cascaded stack or if a link is removed from the cascaded 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 running IOS software  
Release 12.0(5)XU or later, Release 12.1(6)EA2 or later for Catalyst 2950  
switches, and Release 12.1(4)EA1 or later for Catalyst 3550 switches.  
For Catalyst 2900 XL and 3500 XL switches running IOS software earlier than  
Release 12.0(5)XU, an illegal loop is created under these conditions:  
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  
Removing a GigaStack GBIC  
Caution  
A loop causes excessive collision errors on the port and can cause the link to  
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 connected through its GigaStack GBIC to another switchs  
GigaStack GBIC that does not support loop detection, the GBIC LEDs turn these  
colors:  
The GigaStack GBIC LED on the switch without loop detection turns green  
almost immediately.  
The GigaStack GBIC LED on the switch with loop detection flashes green for  
15 seconds and then turns 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 through the stack, and the GigaStack GBIC LEDs  
remain green.  
To avoid problems with loop configurations, make sure that all switches in your  
stack are running the appropriate IOS release as shown in Table 1-5 on page 1-8.  
For more information, see the Minimum IOS Release for Redundant Loop  
Configurationssection on page 1-7. For switch software upgrade information,  
refer to the release notes for your switch.  
Removing a GigaStack GBIC  
Remove a GigaStack GBIC as follows:  
Step 1  
Step 2  
Release the GigaStack GBIC from the slot by simultaneously squeezing the two  
plastic tabs (one on each side of the GigaStack GBIC).  
To remove, slide the GigaStack GBIC out of the slot. A flap drops down to protect  
the internal connector.

Power-On Self-Test  
Step 3  
Step 4  
If you are using the GBIC clip to secure the GBIC cables, remove the clip from  
the GigaStack GBIC by pulling the tabs from the slots on the GBIC. Remove the  
cables from the notches in the clip.  
Disconnect the cable from the GigaStack GBIC port.  
Warning  
Ultimate disposal of this product should be handled according to all national  
laws and regulations.  
Power-On Self-Test  
All supporting switches perform a power-on self-test (POST) on the GigaStack  
GBIC. When you insert the GigaStack GBIC into the switch or module slot, the  
port LED on the switch or module turns amber while STP checks for possible  
loops and then turns green. When you insert a GigaStack GBIC cable into the  
GBIC port, the GigaStack GBIC port turns green if there is network connectivity;  
no additional configuration is needed. For more information about the LED  
meanings, see the GigaStack GBIC LEDssection on page 1-2 and the GBIC  
Module Slot LEDssection on page 1-3.

color for more than  
1 minute.  
Link flap (the link keeps  
going up and down).  
Remove and reinsert the GigaStack GBIC.  
Upgrade all the switches in a series to the same  
software version; otherwise, the loop-breaking  
algorithm might never resolve itself. For example,  
if the stack includes only Catalyst 2900 series XL  
and 3500 series XL switches, they must run  
Release 12.0(5)XU or later. If the stack includes a  
mixture of Catalyst 2900 series XL,  
3500 series XL, 2950, and 3550 switches, all the  
2900 XL and 3500 XL switches must run  
Release 12.0(5)XW or later, all Catalyst 2950  
switches must run Release 12.1(6)EA2 or later,  
and all Catalyst 3550 switches must run  
Release 12.1(4)EA1 or later.  
If no loop exists in the GigaStack GBIC stack, you  
can disable the loop-breaking algorithm by using  
the no gigastack loop-breaking [interface-id]  
global configuration command.
