If hard disk errors are reported, you must replace the 
hard disk. See Removing and Replacing a Faulty Hard 
Disk on page 143. If hard disk errors are not reported and 
if your RSD copy of the hard disk did not contain the 
latest database, restore the current database from your 
DATA SAVE RSD. See Restoring the Database from a 
DATA SAVE Backup on page 128 (note: you may need 
your Mitel Options Password).
If you don’t have an RSD copy of the hard drive (a VOL 
BACKUP)
1. Perform a DATA SAVE to RSD. See Making a DATA 
SAVE Backup on page 164.
2. Load the operating system software from the RSD (see 
page 171).
3. Restore the database (see page 174).
4. Enter:

If hard errors are reported, you must replace the hard 
disk. See Removing and Replacing a Faulty Hard Disk 
on page 143. If hard disk errors are not reported and if 
your RSD copy of the hard disk did not contain the latest 
database, restore the current database from your DATA 
SAVE RSD. See Restoring the Database from a DATA

5. Enter VOL DISABLE SYSUSER on the plane with the 
faulty hard disk (inactive plane).
6. Power down the control node (see page 136).
7. Remove the cabinet sleeve.
Wear an anti-static wrist strap.
8. Remove the power cable from rear of the hard drive. 
Disconnect the power cable from the rear of the RSD 
drive directly below the hard disk drive being replaced. 
In a redundant control node, it isn’t necessary to remove 
the power cable from the RSD drive if you are replacing 
disk drive B.
9. Disconnect the ribbon cable from the rear of the hard 
disk drive. 
10. From the front of the node, remove the two screws that 
hold the drive carrier in place.
11. Gently slide the drive carrier from the node and remove 
the four screws (two on each side) that hold the disk 
drive in place.
12. Unpack the replacement disk drive. Ensure that the 
address straps (A0, A1, A2) are removed and remove 
the bus terminators from the drive. 
13. Replace the hard disk drive.
14. Connect the power and ribbon cables.
15. Connect the external ac power cord(s) at the rear of the 
node.
16. Set the power switch(es) on the rear of the node to “I” 
(ON).
17. Enter VOL E SYSUSER to enable access to the sysuser 
volume.

18. If the operating system software was not installed on the 
replacement hard disk at the factory, you must load the 
operating system software. For non-redundant systems,

Replacing Circuit Cards
Hazardous voltages can exist on installed peripheral cards 
even when power is removed from the system. Grasp cards 
by the lock latches only. Do not touch the sides of cards.
You can replace peripheral interface or DSU cards while the 
node is operating.
Removing a Card
1. Enter:
BUSY 
Select the COURTESY DOWN option.
2. To confirm that all circuits are in the busy state, enter:
STATE 
Wear an anti-static wrist strap whenever you handle 
circuit cards.
3. Pull the upper and lower latches outward until they are 
both in the horizontal release position.
4. Draw the card toward you.
5. Immediately place the card in an anti-static bag.
Installing a Card
1. For cards that have switches, refer to the card’s hard-
ware description for information about switch settings.
Wear an anti-static wrist strap whenever you handle 
circuit cards.
2. Check the connector pins to be certain that they are 
straight.
3. Slide the card into the slot.

4. Push the upper and lower latches away from you until 
they are vertical and the card is locked in place.
5. To return the circuits to service, enter:
RTS 
Replacing a Main Controller Card
When you replace a Main Controller (MC) card, ensure that 
the programmed MC card and the installed MC card match. 
If they do not match, no links are assigned.
1. Remove the front panels.
2. Perform a DATA SAVE to RSD. See Making a DATA 
SAVE Backup on page 164.
3. If you have a redundant system:
- Switch activity to the plane with the healthy Main 
Controller card.
- Hold down PANEL ENABLE and press ACTIVITY 
FREEZE ON.
- Enter FILE STAT REDUN from the active plane and 
then from the inactive plane. Both planes should be IN 
SYNCH. If they are not, see Table 25 Status of 
Redundant File System (page 125)
4. Enter:
DBMS STAT
The DBMS initialized flag should be ON.
5. Enter VOL DISMOUNT SYSUSER (from the inactive 
plane).
Power down the control node before removing the 
MC card. Powering down the node takes the system 
out of service.
6. Set the power switch on the (inactive plane) power 
distribution unit at the rear of the cabinet to “0” (OFF). 
						

							Technician’s Handbook

7. Disconnect the (inactive plane) power cord from the 
power source.
Wear an anti-static wrist strap whenever you handle 
circuit cards.
8. Replace the old MC card with the new MC card.
Note:If you have an ETI card installed, disconnect and then 
reconnect the cables as required.
9. Power up the control node (see page 138).
10. If you have a redundant system:
- From the inactive plane, enter FILE STAT REDUN.
- When the system is IN SYNCH, hold down PANEL 
ENABLE and press ACTIVITY SWITCH OFF.
11. Replace the front panels.
Replacing a Peripheral Switch Controller (PSC) Card
1. If you have a redundant system, hold down PANEL EN-
ABLE and press ACTIVITY FREEZE ON.
Step 2. takes the peripheral devices connected to the 
node out of service.
2. Power down the peripheral node (see page 136).
Wear an anti-static wrist strap whenever you handle 
circuit cards.
3. Replace the faulty PSC card with the new PSC card.
4. Power up the peripheral node (see page 138).
5. Hold down PANEL ENABLE and press ACTIVITY 
FREEZE OFF.

Replacing a Control Resource Card (CRC)
1. If you have a redundant system, hold down PANEL 
ENABLE and press ACTIVITY FREEZE ON.
Power down the control node before removing the 
Control Resource card. Powering down the node 
takes the system out of service.
2. Power down the main control node (see page 136).
Wear an anti-static wrist strap whenever you handle 
circuit cards.
3. If the system has a CRCIII, disconnect the two modular 
cables from the faceplate of the card.
4. Slide the CRC out of the cabinet.
5. Remove the system ID module from the connector J1 on 
the faulty card.
6. Plug the system ID module into connector J1 on the 
replacement CRC. The system ID module can be 
installed only one way. Ensure that you align the pins 
correctly.
7. Set the DIP switches on the replacement CRC faceplate 
to the same settings as those on the faulty CRC.
8. Insert the replacement CRC into its cabinet slot.
9. If the system uses a CRCIII, reconnect the modular 
cables to the same ports on the replacement CRC III 
faceplate.
10. Power up the main control node (see page 138).

Replacing CEPT or DS1 Formatter Cards with 
DS1/CEPT I or II Cards
If your system software is Lightware 31 R1.0 or higher, use 
the CEPT Formatter II (MC269CA) or DS1/T1 Formatter II 
(MC270CA) cards for replacement.
If your system software is Q10.7.14 or higher, use the CEPT 
Formatter I (MC264CA) or DS1/T1 Formatter I (MC263CA) 
cards for replacement.
1. Connect a laptop computer to the card by using a 
straight through serial cable or anull modem adapter. 
2. If using a modem:
- Set the modem DIP switches for initial setup according 
to the manufacturer’s suggestions.
- Connect a PC to the modem, launch a VT100 
emulation session, and set the serial port settings to: 
Speed = 38400, Data bits = 8, Parity = none, and Stop 
bits =1.
- Enter the modem command settings (according to your 
type of modem), then power down the modem.
- Change the modem DIP switch settings to normal 
operation.
3. Connect the modem or straight through cable, from a 
laptop or PC, to the replacement card and access the 
maintenance window.
4. Run acommunications package for VT100 terminal 
emulation (dumb terminal) and set to 8 bits, no parity, 1 
stop bit, and 38400 baud rate.
5. Enter the following information for each DS1/CEPT 
Formatter I card:
- Signaling type (CAS or DPNSS)
- D-channel inversion for T1 DPNSS
- Main control version (either prior to, or after, Q10.7.8).
- Line length for T1
Note:See “DS1/CEPT Formatter I Card (MC263CA and MC264CA) 
Communications” on page 111 for information on inputting the 
information.
