Installing the Adapter

This section contains information on installing the A6825A or A6847A adapter in an OpenVMS system.




	WARNING! The installation procedures in this section require opening the computer cabinet, which might expose you to high-energy (high-amperage) circuits and sharp edges in the equipment chassis. Ensure to remove all rings, watches, and other jewelry before opening the cabinet.




	CAUTION: The adapter contains electronic components that can easily be damaged by small amount of static electricity. To avoid damage, use the following guidelines: Store the adapter in its antistatic plastic bag until you are ready to install it. Work in a static-free area, if possible. Handle the adapter by the edges only. Do not touch electronic components or electrical traces. If you must lay the adapter down, place it on a non-conductive mat or surface. Use the ESD kit that is provided with the adapter. Follow the instructions included with the kit. Use a suitable ground—any exposed metal surface on the system chassis.

Before beginning the installation, and without removing the adapter from its antistatic bag, inspect the adapter for any sign of obvious damage, such as chipped or loose components. Contact Hewlett-Packard if the adapter is damaged.

Install the Card

To physically insert the card into your system, perform these steps:

Shut down the system.
Insert the card into an empty PCI slot.
Connect the card to the network.
Power up the system. When the system is up, any error messages will appear on the terminal display or system console.

See the hardware documentation for the card for details.

Boot the System

Log in as SYSTEM.
Check the OpenVMS version by executing SHOW SYSTEM. The version must be V8.2 (or later).




	NOTE: The LAN driver for this card is included in the OpenVMS installation.

Configure the Card Using LANCP

Log in as SYSTEM and verify that the card and its hardware path are displayed by executing

MC LANCP SHOW CONFIG

The LAN device characteristics that can be set include speed, duplex mode, flow control, and whether jumbo frames are enabled. The MC LANCP SET DEVICE and LANCP DEFINE DEVICE commands modify these settings.
Set the desired characteristics according to the Network Configuration worksheet (see Table 2-1 “Network Card Configuration Worksheet”). For example, use this command:

MC LANCP DEFINE DEVICE devname /SPEED=1000 /FULL /AUTONEGOTIATE

Table 2-1 Network Card Configuration Worksheet

Data Type	Required/ Optional	Default	Where to Configure	Example
Station address	Built-in but can be optionally changed	As shown on card	not configurable	0x0060b0c4012f
Link configuration	Optional	Autonegotiating	LANCP	MC LANCP SET DEVICE/AUTO
Link speed/duplex mode	Optional	Autonegotiating	Hub or switch^[1] or LANCP	MC LANCP SET DEVICE/ SPEED=1000 /FULL
MTU (Maximum Transmission Unit): Jumbo Frames	Optional	1518 Bytes	LANCP	MC LANCP SET DEVICE/JUMBO
Flow control	Optional	On	LANCP	MC LANCP SET DEVICE/FLOW
^[1]The speed configuration of the 1000Base-T can be 10, 100, or 1000 Mbps and is determined by the speed setting of the hub or switch port to which the card is connected. The card automatically senses this speed if autonegotiation is enabled. The card only runs at one speed at a time.

Optional Step: Jumbo Frames Size

(Jumbo Frames Size (Jumbo frames are supported only at 1000 Mbit/s)

Jumbo frames for the LAN driver on OpenVMS V8.2 have an mtu_size in the range of 1518-9018 bytes.

Jumbo frames are enabled system-wide by setting bit 6 in the system parameter LAN_FLAGS. To enable jumbo frames on individual devices, use the LANCP command SET DEVICE/JUMBO. To disable jumbo frames, use the LANCP command SET DEVICE/NOJUMBO.

To preserve the setting of jumbo frames across boots, when using LANCP, define the setting in the LANCP permanent device database, using the command DEFINE DEVICE/JUMBO.
