System Firmware (POST & BIOS)

Firmware stored in EPROM.

ROM Images

03F0312 / 03F0313 - 28 Jan 1992, rev. 19h, 2x 27C512 (U77 / U78). Bad checksum?


Memory

2MB ECC?? 56-pin SIMM.

53F7913, individual memory modules are 02G2871.

Note: The second stick ("5494 Memory Expansion Feature") must be installed in order to use the Frame Relay Token-Ring Bridge feature (and possibly for some other functionality as well).


Known Problems

SRC F8F556 (H121724)

Symptom SRC F8F556

SRC F8F556 is a known problem with the Vimercate produced planars. The way to identify Vimercate planars is: near the SIMM there is a label with bars. In this label you can find the P/N 02F9524 and just before it exists a sequence of letters and numbers. If this sequence starts with "WI" this planar comes from Vimercate. Everything else comes from Mechanicsburg. Example: WIJA0890187 02F9524 253

Note: SRC F8F556 Can also be caused by a defected twinaxial adapter card. There is about a 15% probability that the twinax adapter card is the source of the problem.

Problem Isolation Aids

None.

Fix

Replace the planar. If that does not fix it, replace the twinax adapter card.

The planar is most likely your problem so replace it first.
