(4) Excessive Port overrun errors on the DECSERVER 200's using DEC423 inter-connect. (5) Server slowdown due to false logins on the DECSERVER 200's using DEC423 interconnect. **NOTE** The above listed problems only apply to DECSERVER 200's, DSRVB-BA and DSRVB-BB (DECserver 200-DL/DATA LEADS ONLY) models, and will only occur when a terminal is powered off during normal operations. -------------------------------------------------------------------------------- Quick Check 1) Verify DSRVB-BA and DSRVB-BB at Revision "C1" or higher. -------------------------------------------------------------------------------- Compatibility/Prerequisite FCO | Estimated Time to Install NONE | 1.0 Hr. ------------------------------------------------+------------------------------- Special Tools or Test Equipment NONE -------------------------------------------------------------------------------- FCO Parts Information -------------------------------------------------------------------------------- Order by | Contents FCO Kit # +--------------------------------------------------------------- | Quantity Part Number Description ----------------+-------------------------------------------------------------- EQ-01546-01 | 1 DSRVB-BA 120V Ethernet Terminal Switch EQ-01546-02 | 1 DSRVB-BB 240V Ethernet Terminal Switch FA-04851-01 | 1 FCO Document EQ Kit Variation/System-Option Applicability: DSRVB-BA and DSRVB-BB. ------------------------------------------------------------------------------- Approvals ------------------------------------------------------------------------------- CSSE Engineer | F.S.

Whenever power is applied to the unit, the server performs a diagnostic self-test and initiates a request for a down-line load of the server image from a load host. The server self-test normally takes about 20 seconds to complete, but the down line load loading of the server image could take longer if the network is busy. Allow up to two minutes for the server self-test and down-line loading of the server image to complete, then compare the state of the four status LED's on the server with the following table: STATUS LED's ___________________________________________________________________________ | LED | LED | | | | Name | Definition | State | Indication | --------------------------------------------------------------------------- | D1 | Power on/off | ON | The server's dc voltages are correct | | | | OFF | The server's dc voltages are NOT correct | |-------------------------------------------------------------------------- | D2 | Diagnostic | ON | Self-test passed | | | | OFF | Fatal error or test-in-progress | | | | BLINK | Nonfatal error | --------------------------------------------------------------------------- | D3 | Software | ON | Server image successfully loaded | | | | OFF | Down-line load in progress | | | | BLINK | Multiple-load failure | --------------------------------------------------------------------------- | D4 | Network | ON* | Indicates activity on the network | | | Activity | | | -------------------------------------------------------------------------- * Can be ON or OFF or flickering, depending on the amount of traffic on the network. **NOTE** (If the power-up self test diagnostic is not successful consult the DECSERVER 200 Technical Manual for additional information.) 12) Complete LARS data as per example on Page 5 of 5 of this FCO Document. 13) Update the Site Management Guide to reflect installation of this FCO. _ _ _ _ _ _ _ | FCO DSRVB-F001 | | | | | | | | | |d|i|g|i|t|a|l| | PAGE 4 OF 5 |_|_|_|_|_|_|_| | | _______________________________|_________________________________________ Applicability (Continued from Page 1) On Digital Equipment communications systems using DEC423, problems have been known to occur when a user terminal is powered down, or a terminal line is left unterminated. This creates a condition where signal cross-talk from adjacent active lines or noise from other electrical sources is received at the local system or DECserver and the system attempts to act upon the signal received. The usual scenario is one where the system attempts to have the "noise" log-in and fails. The 5180 receiver chip is used in the following Digital products: 1) DSRVB-BA 120V 8 Line Ethernet Terminal Switch (DEC423 Data Leads Only). 2) DSRVB-BB 240V 8 Line Ethernet Terminal Switch (DEC423 Data Leads Only). Problem/Symptoms (Continued from Page 1) 4) Excessive Port overrun errors on the DECSERVER 200's using DEC423 inter-connect. 5) Server slowdown due to false logins on the DECSERVER 200's using DEC423 inter-connect. **NOTE** The above listed problems only apply to DECSERVER 200's and DSRVB-BB (DECSERVER 200-DL/DATA LEADS ONLY) models, and will only occur when a terminal is powered off during normal operations. _ _ _ _ _ _ _ | FCO DSRVB-F001 | | | | | | | | | |d|i|g|i|t|a|l| | PAGE 5 OF 5 |_|_|_|_|_|_|_| | | _______________________________|_________________________________________ LARS CATEGORY F USA GIA EUROPE Activity - Contract and Warranty W U Y Non Contract/Non Warranty F F F RTD/Off-site Agreement F DEC Option DSRVB DSRVB DSRVB Type of Call M M M Action Taken D D I Fail Area-Module-FCO-Comments DSRVB-F001 DSRVB-F001 DSRVB-F001 Material Used EQ-01546-01 EQ-01546-01 EQ-01546-01 Material Used EQ-01546-02 EQ-01546-02 EQ-01546-02 (a) Warranty Optimum, Warranty Standard and Warranty Basic (on-site) Agreements.
