(Refer to Figure 3-30 on page 3-49.) D. CONNECT THE TWO CABINETS TOGETHER 6.11 To install an expansion cabinet underneath the main equipment cabinet and connect the two together, perform the following steps: (1) If not already done, remove the front door and back panel from the main equipment cabinet as outlined on page 3-39. (2) Screw the four lifting handles into the holes pro- vided on the main equipment cabinet (as shown below). (3) With one person at each comer, carefully lift the main equipment cabinet up and place it securely on top of the expansion cabinet. A fully loaded equipment cabinet can weigh sever- al hundred pounds. To avoid injury, use proper lift- ing technique and exercise extreme caution. (4) At each of the four comers, use a y4-20 X J&inch bolt and a star washer to secure the main equipment cabinet to the expansion cabinet (as shown below). ;: (5) Route the free end of the expansion power cable (withthefivelargeconnectors)upthebackofthe equipment cabinet, in through the soffit (cable shelf), and out to the front of the cabinet. (6) Connect one end of the V-ring power cable to the appropriate connector on the front side of the main power supply chassis. (Refer to Figure 3-30 on page 3-49.) (7) While sliding the expansion power supply chas- sis into place (the bottom edge of the chassis fits under a metal lip that is to the left of the main chassis), connect the free end of the V-ring power cable to the appropriate connector on the front side of the expansion power supply chassis. (Re- fer to Figure 3-31 on page 3-50.) (8) Using three, 8-32 x @rich screws with wash- ers, secure the bottom of the expansion power supply chassis to the equipment cabinet. (9) Reaching in through the front of the cabinet, at- tach the five large connectors on the end of the expansion power cable to the appropriate con- nectors on the expansion power supply chassis.

INTER-TEL PRACTICES IMXfGMX 4161832 INS TALLATION & MAINTENANCE INSTALLATION Issue 1. November 1994 E. INSTALL TECE POWER SUPPLY MODULES CAUTION HIGH VOLZdGE. When the system power is turned on, each module contains both 35OVDC and 11OVAC. Before inserting or removing the power supply modules, make sure that the AC POWER switch has been turned OFF for at least five min- utes. Failure to allow the high voltage to dissipate can cause bodily injury. 6.12 After the main power supply chassis and, if nec- essary, the expansion power supply chassis have been installed (as outlined on page 3-4S), install the power supply modules as follows: NOTE: Refer to pages 2-10 and 2-11 in SPECIFICA- TIONS for information concerning module compatibil- ities and special Tl requirements. (1) On each power supply, ensure that the AC power cable is not plugged in and the AC POWER switch is OFF. (2) At the rear of the cabinet, remove the screws to the back cover(s) of the power supply chassis, and set the cover(s) aside. NOTE: For easier power supply module remov- al, each version C power supply chassis is shipped with an extractor tool attached to the in- side of the back cover. The extractor tool may be used with version B and C modules only. (3) With the components facing right, insert the power supply modules in the appropriate slots. (Refer to Figures 3-32 and 3-33 on the following pages for slot locations.) Note the following re- quirements: CAUTION When inserting the power supply modules, be sure that each module is fully seated in the appropriate slot. If a module is not securely seated when power is turned on, the power supply and circuit cards may be damaged. l The main power supply chassis must be equipped with two Quad Modules, one Mas- ter 30V Module, one -48V Module, and one Ring Generator Module. l If an expansion power supply chassis is in- stalled, it must be equipped with one Quad Module and one Master 30V Module. l Depending on the number and type of keysets to be connected to Keyset Cards (DKSCs, 1 KSCs, or KSC-Ds) in the main equipment cabinet, one or two Slave 30V Modules may also be needed in the main power supply chassis (see page 2-10 for details). l Depending on the number and type of keysets to be connected to Keyset Cards in the expan- sion cabinet, one or two Slave 30V Modules may also be needed in the expansion power supply chassis (see page 2-10 for details). l If any Single-Line Cards (SLCs), Inward Dialing Cards (IDCs), Loop/Ground Start Cards (LGCs), or E&M Cards (EMCs) are to be installed in the expansion cabinet, a -48V Module must also be installed in the expan- sion power supply chassis. NOTE: Loop Start Cards (LSCs) and Tl Cards (‘TlCs) do not require a -48V Module. (4) Slide the back cover(s) of the power supply chas- sis into place and replace the screws. II Always replace the back cover before tummg on (5) Plug the AC power cable on the expansion power supply chassis into the AC expansion receptacle on the main power supply chassis. NOTE: DO NOT plug in the system AC power cable until the power supply electrical test, as outlined on page 3-55, has been performed. (6) Ground the system according to the instructions on page 3-54. CAUTION To prevent damage, do not move the equipment cabinet any great distance while the power supply modules are installed. Page 3-51

INSTALLATION INTER-TELPRACTICES Issue 1. November 1994 IMX/GM.X 416/832 INSlYALIATION 8z MAINTENANCE Grounding Requinzments 6.13 The equipment cabinet must be properly grounded to an earth ground point. Acopper, cold water pipe is usually a good ground point NOTE: According to UL 1459, “an insulated grounding conductor that is not smaller in size and equivalent in in- sulation material and thickness to the grounded and un- grounded branch-circuit supply conductors, except that it is green with or without one or more yellow stripes, is to be installed as part of the circuit that supplies the product or system.” Also, “the attachment-plug recep tacles in the vicinity of the product or system are all to be of a grounding type, and the grounding conductors serv- ing these receptacles are to be connected to earthground at the service equipment.” 6.14 The grounding wire should be 1OAWG or larger and should not exceed 25 feet (7.5 meters) to help pro- vide RFI/EMI protection, or should not exceed 10 feet (3 meters) to help provide both RFIEMI and lightning protection. 6.15 To ground the system (see Figure 3-34 below): (1) Ensure that the system’s main AC Power cable is not plugged into the AC outlet. (2) Mount a grounding terminal on the MDF back- board and connect it to: a. An earth ground. b. The ground lug on the back side of the main power supply chassis. c. Battery compartments, if used. d. Trunk gas discharge tubes, if used. 6.16 If AC power-related problems appear on the sys- tem while in operation, one of the following two meth- ods can be used to test the ground. 0 Use a digital multimeter to measure the difference of potential between the equipment cabinet ground point and the power neutral, and between the equip- ment cabinet ground point and the third wire ground. Ifthe voltage measurement exceeds OSV, noise may develop on the system. If this occurs, call an electri- cian. 0 Use a Megger to test the ground point. (A Megger should be available through the local power compa- ny.) The reading should be 5 ohms or less. FIGURE 3-34. EQUIPMENT CABINET GROUNDING ~ #lOGROUND WIRE EARTH GROUND Page 3-54
INTER-TELPRACTICES IMX/GMX 416/832 INSTALLATION & MAINTENANCE INSTALLATION Issue 1. November 1994 Power Supply Electrical Test 6.17 Perform the following electrical check on the power supply(s). (1) Ensure that the main system AC power cable is not plugged in and that the AC POWER switch on the front of each power supply unit is OFF. (2) Check the condition of the fuses located on the power supply(s). a. On the main power supply unit, the main fuse (located on the front) should be: 3OOVAC, 3OA, time-delay Buss SC-30 (or equivalent). The auxiliary fuse (located on the back) should be: 125/25OVAC, lOA, time-delay Buss SC-10 (or equivalent). The expansion fuse (also located on the back) should be: 125/25OVAC, lSA, time-delay Buss SC-15 (or equivalent). b. On the expansion power supply unit, the fuse on the front should be: lzS/zsOVAC, 191, time-delay Buss SC-15 (or equivalent). NOTE: Since the fuse on the main power supply chassis also protects the expansion power supply, newer-version expansion power supply chassis are not equipped with a fuse. (3) Plug the surge/spike Protector Provided with the system into a 105-125VAC, 57-63Bx, 3OA, single-phase commercial power source. Since the surge/spike protector is terminated on a NEMA L5-30 twist-lock plug, a compatible AC receptacle (L5-30R) is needed. NOTE: This MUST be an isolated, dedicated circuit. Do NOT use an extension cord when in- stalling the pOwer supply. Also, DO NOT plug any other equipment into the same AC outlet; however, the two auxiliary AC receptacles on the back of the main power supply can be used for connecting external equipment such as the pro- gramming monitor and/or SMDRJSMDA output device(s). (4) Plug the main system AC power cable into the surge/spike protector and turn ON the AC POW- ER switch on the main power supply unit first, then turn ON the AC POWER switch on the ex- pansion Power supply unit. CAUTION When powering up the entire system, turn on the main power supplyfirsz, then turn on the expansion power supply. (See page 2-10 for details.) Newer- version main power supply chassis have been modi- fied so that turning off the AC power switch will also turn off the expansion supply. (5) Measure the following system voltages. A digi- tal voltmeter of fo.5% accuracy is required. a. Referring to Figure 3-25 on page 342, Fig- ure 3-28 on page 3-46, and the chart follow- ing step b, measure the applicable voltages on the back of the main Telecom Mother- board and, if installed, the expansion Tele- corn Motherboard. Use ground as a reference. The measurements should be within the limits listed in the chart below. (If necessary, remove each power cable connec- tor one at a time and measure the voltage in- side the connector.) b. Referring to Figure 3-35 on page 3-57 and the chart below, measure the applicable volt- ages on the free ends of the PC Motherboard power cable, the two disk drive power cables, and the HDLC power cable. Use ground as a reference. The measurements should be within the following limits: -5VDC km%=xJ +5VDC a-%~ -12VDC s-%vJJc +12VDC *2o?bVDC +3OVDC &2o%VDC -4wDc ti(=,v=J VRING (9OVAc) tiO’%VAC FWR ALARM (+4.5VJx) ~20?6VDC CFTJP (+5W ti~vD(-J CPcN WSVDC) so%= NOTE: The CPCP measurement should be .7V (fo.2OV) higher than the actual +5V measurement. The CPCN measurement should be .7V (fo.2OV) lower than the ac- tual ground measurement. I (6) If the voltages am within the specijied limits, skip to step 8. If voltage measumnents are not within the speci- fied limits, remove the power cable(s) from the power supply(s) and check the voltages directly at the individual connectors on the front of the main and/or expansion power supply units. Refer to Figures 3-36 and 3-37 on pages 3-58 and 3-59. Page 3-55
INS’E4LLATION Issue 1, November 1994 INTER-TELPRACTICES IMX/GMX 416/832 INSTALLATION 8z MAINTENANCE (7) If the voltages at the individual connectors aiz within the specifwd limits, replace the defective cable(s). If voltage measuremertls at the individual con- nectors am not within the specijied limits, re- place the defective power supply module(s) and/or the power supply chassis(s). (8) Turn OFF the AC POWER switch. CAUTION If using a hard disk drive that does not have %elf- parking” heads: When powering down the entire system, first “park the heads” on the hard disk drive (as outlined on page 3-154), then turn off the muin power supply first before turning off the expansion power supply. This sequence allows the hard disk drive to shut down properly; the reverse does not al- low proper shutdown and may damage the hard disk drive. (See page 2-10 for additional information.) Newer-version main power supply chassis have been modified so that turning off the AC power switch will also turn off the expansion supply. Page 3-56
