SHBBook Page 4 Wednesday, March 3, 1999 8:03 PM Installation Cabling and Voltage Requirements This section describes the cabling and voltage requirements for the NetStacker II 12 port and 24 port hubs. ◆ Note: You may connect network cable segments to the hub or disconnect them while the power is on. Plugging in or removing cables while your hub is running will not interrupt the traffic or disrupt the operation of the hub.
SHBBook Page 5 Wednesday, March 3, 1999 8:03 PM Placement and Mounting Placement and Mounting This section describes how to mount the NetStacker II on a desktop or shelf. Hub Location The location chosen for the NetStacker II hub should be less than 100 meters from servers, workstations, and other devices. ▲ Important: Category 5 cables are environment-sensitive. Make sure that the cable route is not too close to electromagnetic noise sources such as power lines or fluorescent lights.
SHBBook Page 6 Wednesday, March 3, 1999 8:03 PM Installation 3 Place the device into the 19-inch rack and attach it firmly. Ensure that the ventilation holes do not get blocked.

SHBBook Page 8 Wednesday, March 3, 1999 8:03 PM Installation 2 Make sure that the length of the straight through cable between the NetStacker II and a 100Mbps repeater does not exceed 5 meters, including all patch cables and cross connect wires. The cable between the NetStacker II and any switch or any 10Mbps repeater cannot exceed 100 meters. ◆ Note: If you need to connect more than 2 hubs via 100Mbps connections, you must have a switch separating the additional hubs.

SHBBook Page 10 Wednesday, March 3, 1999 8:03 PM Installation Stacking Hubs Up to eight NetStacker II hubs may be connected within a stack. Furthermore, a management module can be installed easily in any of the stacked hubs, so that all of them can be managed. The management module communicates with a manager console by means of SNMP agent software, installed in the managed hub. This reduces considerably the expense of equipping each hub for management.
SHBBook Page 11 Wednesday, March 3, 1999 8:03 PM Connecting Network Devices Adding Fiber Optic Connectivity via MII To add connectivity for 100Base-FX transmission media, insert the optional MII fiber-optic module in the MII Module Slot in the back panel of the hub, as shown in Figure 2-11. If you have not installed a management module, this slot will be available for the fiber-optic connection module.
SHBBook Page 12 Wednesday, March 3, 1999 8:03 PM Installation Powering on the Hub The NetStacker II hub may be turned on with (or without) LAN segment cables connected. To power on the hub: 1 Connect one end of the power cord (supplied) into the AC power connector on the back panel of the hub. ◆ Note: NetStacker II hubs are equipped with an internal power supply. Power sensing is automatic for all international utility power. 2 3 Connect the power cord to a local power source outlet.
SHBBook Page 1 Wednesday, March 3, 1999 8:03 PM 3 LED Indicators This chapter explains how to interpret the front panel LED indicators on NetStacker II dual speed hubs. There are no LEDs on the rear panel. The LEDs are used to facilitate monitoring and troubleshooting. These LEDs are: ❑ Power ❑ Collision Indicators ❑ Hub ID Number ❑ Port Link Activity indicators The front panel LEDs of the 12 port and 24 port hubs are shown in Figure 3-1 and Figure 3-2.

SHBBook Page 3 Wednesday, March 3, 1999 8:03 PM Hub ID Number LEDs Hub ID Number LEDs The Hub ID LEDs are a numbered row of eight green LEDs. If your NetStacker II hub is configured with other NetStacker II hubs in a stack, each hub will get an auto-configured ID number, and the LED for that number will be lit on each hub. If your hub is not part of a stack, the LED for ID number 1 will be lit.
