Action: Crew should verify via telemetry
and vacuum meter the actual Cabin
Pressure and report to MCC. Decision to
open KSD pressure relief valve will be
471
made by MCC post analysis. If pressure
relief valve is to be opened, the crew
should go to Soyuz and wait until KSD
valve is re-closed.
Action: Crew will verify actual pressure
reading via telemetry and vacuum meter.
643
No Further crew action is required without
MCC direction.
Action: Monitor Vozdukh status. LIOH
cartridges or CDRA may be activated after 642
MCC conference.
Action: Crew will verify via telemetry the
current status: temp/press and calculate
the rate of decay. May actually have to
undock/land depending upon the situation.
Instrument Compartment normal pressure
is 780 mmHg. If pressure falls below 450
mmHg, Soyuz avionics may not function.

Action: Crew should verify via telemetry
and vacuum meter the actual Cabin
Pressure and report to MCC. Decision to
open KSD pressure relief valve will be
made by MCC post analysis. If pressure
relief valve is to be opened, the crew
should go to Soyuz and wait until KSD
valve is re-closed.

2.301 INT MDM RETRY FAILURE - WARN
(EMER/5A - ALL/FIN)
Page 1 of 3 pages
NOTE
1. This procedure will be executed for C&W message
‘INT MDM Retry Fail - LAB’ - Warning - Event Code
5033.
2. In the event of a failure of the Primary INT MDM, the
‘Primary INT Fail - LAB’ Caution will appear. The
CCS Redundancy Management application will attempt
to Recover the Backup INT MDM.
3. If this should fail after two attempts, the ‘INT MDM
Recovery Fail - LAB’ Caution will be annunciated.
The CCS will then attempt a power cycle of the original
failed INT MDM.
4. If this should fail, then the ‘INT MDM Retry Fail - LAB’
message will appear. At this point, the following
messages should also be in alarm:
‘Primary INT MDM Fail - LAB’ - Caution - Event
Code 5013
‘Backup INT MDM Fail - LAB’ - Caution - Event
Code 5019
‘INT MDM Recovery Fail - LAB’ - Caution - Event
Code 5027
Both MDMs have been power cycled once in this
process.
5. If the failure was specific to the INT MDMs (i.e., not a
LAB wide power failure), the LA and AL MDM will
continue to operate in Minimal Operations in their last
commanded state. Although operating, the LA MDM
data, and data obtained through the LA MDMs will all
appear static on displays.

Notify MCC-H of emergency condition and corrective steps taken as soon
as possible.
With one EETCS loop shut down there is no heat being rejected from the

NOTE
1. Both loops are contaminated with ammonium hydroxide.
The LAB must now be configured to allow isolation of the
affected IFHX and provide cooling to critical avionics. The
NH3 loop associated with the non-leaking IFHX will continue
to provide cooling for the Station. LAB reconfiguration may
be necessary after identifying which NH3 loop is affected by
the leaking IFHX. The leaking IFHX will always be placed in
the Bypass configuration.
2. If the leak is isolated to the MTL IFHX, critical avionics
cooling takes precedence over NH3 contamination on both
loops; therefore, the ITCS will remain in Single mode with the
non-leaking HX providing cooling.
