Obtain the Customer's permission and perform normal system shutdown procedures. Refer to the appropriate system manuals applicable to the system involved. 2. Power down the system and remove the covers and panels required to gain access to the DEQNA, (M7504 Module). ******************************************************************** * To assure that AC power has been removed from the unit, the AC * * power cord must be disconnected. Do not remove any FRU's with * * power applied to the unit. * ******************************************************************** 3. Disconnect the cabinet kit cable from the M7504 module and remove the M7504 module from the system. 4. Verify that jumper W1 (located just behind the LEDS) on the new module corresponds to the position of W1 on the old module. 4A. If the DEQNA is used in a TARGET system (i.e. one that is down line loaded over the network, like an LPS40), you may wish to take the station address PROM from the old module and switch it with the PROM on the new module. This is not a necessary step, and depends on the customer's application. If you don't replace the Address PROM, you will have to change the Host system DECnet database to reflect the new Ethernet address. Instructions for replacing the Station Address PROM are in the DEQNA User's Guide (EK-DEQNA-UG). 5. Replace the new module into the original slot and reconnect the cabinet kit cable. 6. Power up the system and observe the M7504 module for normal power-up microdiagnostic completion. All three LEDS should turn off. Completion of this test verifies successful installation of the DEQNA. No further module testing is required. 7. Replace all covers and panels and return the system to the customer.

If the system is a target µVAX II system and you did not change the Ethernet address PROM, the new Ethernet address can be obtained from the console. At the console prompt (>>>), type E/P/W/N:5 20001920 . The new Ethernet address will be in the last two bytes of each word. For example: >>> E/P/W/N:5 20001920 20001920/ FF08 20001922/ FF00 20001924/ FF2B 20001926/ FF02 20001928/ FFBA 2000192A/ FF0C The new Ethernet address would be 08-00-2B-02-B A-0C. If the system is a target PDP11, the address can be obtained by examining 1774440 and the next 5 locations using ODT. The address will be in OCTAL and must be converted to HEX to be useful. Both of these examples assume that this is the only DEQNA in the system. 9. Complete LARS data as per example on Page 4 of this FCO Document. 10. Update the Site Management Guide to reflect installation of this FCO. _ _ _ _ _ _ _ | FCO DEQNA-O002 | | | | | | | | | |d|i|g|i|t|a|l| | PAGE 4 OF 4 |_|_|_|_|_|_|_| | | _______________________________|_________________________________________ LARS CATEGORY O USA GIA EUROPE Activity - (a)Contract and Warranty W U Y (b)IN-DEC Contract & Warranty K Hardware Segment Code 111 Non Contract/Non Warranty F F F (c)RTD/Off-site Agreement F Product Line 01 DEC Option DEQNA DEQNA DEQNA Type of Call M M M Action Taken D D I Fail Area-Module-FCO-Comments DEQNA-O002 DEQNA-O002 DEQNA-O002 Material Used EQ-01551-01 EQ-01551-01 EQ-01551-01 Material Used EQ-01551-02 EQ-01551-02 EQ-01551-02 (a) Warranty Optimum, Warranty Standard and Warranty Basic (on-site) Agreements.
