2. 40 PCI ESCON Adapter Installation Guide TCP IP Routing TCP IP Direct Connect is a Network Driver Interface Specification NDIS compliant adapter driver TCP IP Direct Connect makes the PCI ESCON Adapter appear exactly like any other Network Interface Card NIC to the Windows server As a result when TCP IP Direct Connect and a PCI ESCON Adapter are installed along with one or more Local Area Network LAN adapters the Windows server becomes a multihomed system Microsoft s Windows 2000 and NT TCP IP protocol stack is capable of performing static IP routing in multihomed servers Static IP routing may be used to route TCP IP traffic across the PCI ESCON Adapter to the IBM mainframe This chapter discusses how to configure both your network and Windows server to take advantage of this capability Sample Configuration 207 168 12 67 pea 207 168 12 1 Am 207 168 12 68 207 168 12 2 207 168 12 4 nn pa 207 168 12 3 Figure 5 24 Network with 2 Subnets Figure 5 24 shows a simple network made up of two sub networks connected by a router A single Windows server is installed on the Token Ring Windows 95 and or 98 is installed in all workstations An IP subnet mask of 255 255 255 192 is being used to allow for four subnets with IP addresses as follows TCP IP Direct Connect 41 Subnet 0 207 168 12 1 207 168 12 62 Subnet 1 207 168 12 65 207 168 12 126 Subnet 2 207 168 12 129 207 168 12

Chapter 2 HARDWARE INSTALLATION Installing the Adapter CAUTION ESCON Connedtor Serial Port The PCI ESCON Adapter is a PC adapter card and as such can be damaged by Electrostatic Discharge Before removing the adapter from it s protective static bag please ensure that you are free of static charge At minimum you should ground yourself to the system you are using The PCI ESCON Adapter is a full size PCI adapter measuring 12 283 X 4 2 inches Figure 2 1 The adapter hardware comes pre configured and is ready to be installed There are no jumpers or switches that need setting prior to installation m ye Figure 2 1 Bus Tech s PBSA Adapter Installation procedures of the physical adapter vary depending on hardware platform manufacturer but have some commonalties among vendors These steps should guide you through a successful installation of the ESCON adapter Step 1 Ensure the PCI system is powered down The ultimate assurance of this fact is to remove the power cable from the rear of the system where possible 2 Remove the system cover as outlined by the system hardware manufacturer generally by removing the cover screws and sliding off the cover to expose the interior of the system 3 Determine an available slot for installation of the adapter The adapter requires a full length PCI slot Often systems will have PCI slots which will not support full length adapters because of processor placement This is
5. As shown in Figure 4 1 Controller 1 is attached directly to one of the mainframe s ESCON channels Assuming the mainframe is running a single Logical Partition LPAR this is simplest option for connecting an ESCON controller to the mainframe However connecting an ESCON controller directly to a mainframe s ESCON channel in this fashion imposes two restrictions 1 Only a single controller can be attached to a mainframe s channel 2 The controller is only able to communicate with a single mainframe the one it is physically attached to An ESCON director overcomes these restrictions by attaching multiple downstream controllers and by supporting multiple ESCON interfaces to multiple mainframes In Figure 4 1 Controllers 2 4 are connected to the director which is then connected to two ESCON channels one on each of two mainframes Some mainframes also support multiple Logical Partitions LPARs running on a single system logically making the system appear as multiple computers The ESCON Multiple Image Facility EMIF can be used in those environments to allow sharing of ESCON channel paths across partitions In Figure 4 1 a single channel path defined between the mainframe and Controller 5 can be shared by both LPAR P1 and LPAR P2 using EMIF ESCON Configuration 15 Finally using both ESCON Directors and EMIF it is possible for a single ESCON controller to communicate with multiple Logical Partitions LPARs running o
