Procedure

Update MAC address (DHCP only)

If using an SD Card, simply remove the card from the old motherboard and place it in the new one and skip this section. If using DHCP, you must update the MAC address in dhcpd.conf.

  • Make note the two MAC addresses of the old motherboard (CTRL0 and CTRL1).

  • Locate the MAC address on the new motherboard. The sticker with the MAC address of the CTRL0 interface is located on the bottom of the IMG 1010 near the front panel. The MAC address for the CTRL1 interface is one hex digit higher. See sample dhcpd.conf file in the IMG WebHelp.

  • Edit the dhcpd.conf file located in the /etc or /etc/dhcp directory (depending on OS version) on the GCEMS server. A sample MAC address entry in a dhcpd.conf file is shown in bold below:

host IMG_CPU1_0
{
hardware ethernet 00:20:1C:xx:xx:xx;

  • Locate both MAC address entries for the old motherboard. Change each MAC address to the corresponding address for the new motherboard.

  • Save dhcpd.conf file.

Remove existing tray.

AC Chassis

  • Set power to OFF (O) at rear of docking station.

  • Loosen the two ejector captive fasteners located on each side of the front panel.

  • Lift the ejectors upward and pull to unseat tray from docking station.

  • Slide tray completely out. If returning the tray to Sangoma, contact Sangoma Technical Support.

DC Chassis

  • The DC tray is hot swappable so there is no on/off switch on rear of panel.

  • Loosen the two ejector captive fasteners located on each side of the front panel.

  • Lift the ejectors upward and pull to unseat tray from docking station.

  • Slide tray completely out. If returning the tray to Sangoma, contact Sangoma Technical Support.

Install New Tray

  • Align rail on each side of the tray with the guides on the inside of the docking station.

  • Ensure the ejectors are in the up position.

  • Slide the tray in until the power connectors and signal connectors initially mate. The ejectors will start to move down

 

Important! The guides only provide gross alignment to the power and signal connectors. The guide pins on the main board and I/O card are self aligning and provide exact alignment for the connectors. 

Important! The tray guides also acts as the conduit for any Electrostatic Discharge (ESD) as the tray initially mates with the docking station.

  • When the tray is seated and the connectors are mated, push the ejectors down and tighten captive fasteners.

  • For the AC tray, set power to ON (1) at rear of docking station.

  • If you are using DHCP, observe the front panel to ensure that the IMG gets its IP address from DHCP as well as its configuration.
