Accessories 2 - 11 LED Charge Indications The charge LED shows the status of the battery charging in the mobile computer. The Standard Battery usually charges in less than four hours and the Extended Life Battery usually charges in less than six hours. See Table 2-1 on page 2-5 for charging status indications. Speed LED The green Speed LED lights to indicate that the transfer rate is 100 Mbps. When it is not lit it indicates that the transfer rate is 10Mbps. Link LED The yellow Link LED blinks to indicate activity, or stays lit to indicate that a link is established. When it is not lit it indicates that there is no link. Daisychaining Ethernet Cradles To connect several cradles to an Ethernet network, up to four (recommended maximum) Ethernet cradles may be daisychained. The Speed LED and the Link LED on the Ethernet port 2 function in the same way as the Speed LED and the Link LED on the front of the cradle. To daisychain cradles: 1. Connect the first Ethernet cradle to power and to the Ethernet Switch as shown on Figure 2-5 on page 2-8. 2. Connect power to the second Ethernet cradle. 3. Connect the daisychain Ethernet cable (either straight or twisted cable can be used) between Ethernet Port 2 of the first cradle, and Ethernet Port 1 of the second cradle. 4. Connect additional cradles as described in Step 2 and Step 3. See Table 2-2 for bandwidth limitations. Ethernet Port 2 Speed LED Link LED Ethernet Port 1 Figure 2-11 Daisychaining Four Slot Ethernet Cradles Bandwidth Considerations when Daisychaining Each cradle added to the daisychain impacts the bandwidth allocated to each of the inserted mobile computers, particularly when the mobile computers attempt to send and receive at data rates that exceed the bandwidth provided to the chain (typically 100 Mbps). If a mobile computer in a daisychained cradle does not use its bandwidth, that bandwidth is available to other inserted mobile computers.
