Description of the Module
Functional Description
The 1-Port DS3 IMA (Inverse Multiplexing over ATM) module combines the fea-tures of the 1-Port Channelized DS3 Multiservice module (see the PacketStar®
PSAX 1-Port Channelized DS3 Multiservice Module User Guide) and the 6-Port DS1
IMA module (see the PacketStar® PSAX 6-Port DS1 IMA Module User Guide). It
allows you to configure up to 28 virtual T1 ports for native DS1 ATM services or for as many as 14 independent IMA groups. This gives you point-to-point band-width options between that of a single T1 line and that of a T3 line.

Performance and Power Specifications
Table 2 provides the chassis speed, power consumption, and memory allocation specifications for this module.
Module Placement
The 1-Port DS3 IMA module is installed in any PSAX chassis slot intended to con-tain an I/O or server module. If you are installing the module in a newly installed PSAX chassis, be sure to follow your facility site plan for placing this module in the correct location in the chassis.
Installing the Module
Read the PacketStar®PSAX Safety Guidelines, which accompanies this product,
before proceeding.
WARNING:
!Be sure to use the ejector handles during installation and removal of a PSAX module.
WARNING:
!Make sure the locking tab at the bottom of the module (looking at module in a vertical position) is UP before you insert it into the chassis.
Operating humidity range 5% to 85% relative humidity
Operating altitude range 197 feet below sea level to 13,123 feet above sea level
Storage temperature range -40° to 70° C (-40° to 158° F) Storage humidity range 0 to 90% noncondensing Table 1. Physical Hardware Specifications (Continued)
Specification Description
Table 2. Performance and Power Specifications for the 1-Port DS3 IMA Module Module Total Amount of SDRAM Module Program and Data Space Maximum Input Buffer * Output Buffer† Chassis Speed ‡ Maximum Power Consumption 1-Port DS3 IMA (DS3 IMA) 24 MB 7 MB 4 MB 13 MB (212,992) Low Speed 13 W
* The I/O buffers carry 16,384 cells per megabyte.
† Indicates the size of the output buffer followed by the maximum number of 64-byte cells in the output
buffer.
‡ This column relates only to the speed at which the module communicates within the chassis. A high-speed
module will communicate at high speed (1.2 Gbps) in a chassis that has a high-speed bus (PSAX 4500 chassis). High-speed modules will communicate at 600 Mbps in any other chassis. Low-speed modules will always communicate at 600 Mbps in any chassis.
WARNING:
!When inserting modules into the chassis, slide them gently, not forcefully. Excessive force may cause the modules to be seated improperly in the chas-sis, and result in possible damage to the module or the chassis. Install or remove modules one at a time. Doing this aids in preventing the PSAX sys-tem from indicating any erroneous failure messages, and allows the PSAX system time to reinitialize and display the accurate configuration of the module that is inserted.
Begin
1 Remove the module from its box and ESD protective bag only when you are
ready to install it. Be sure to save the box and the ESD bag to ship the mod-ule in the future if needed.
2 Open the ejector handle at the top of the module faceplate, and slide the
module into an available slot. Be sure to position the module with the ejector handle near the top edge of the chassis opening on the PSAX 1250,
PSAX 2300, and PSAX 4500 chassis. Position the module horizontally in the PSAX 1000 chassis with the ejector handle to the left.
3 Press the ejector handle until it snaps firmly against the faceplate, and verify
that the module is secure in its slot.
4 Insert a flathead screwdriver into the screwdriver slot of the locking tab, and
slide the locking tab down into the locking tab slot (see Figure 2).
Note: Engage the locking tab on modules in the PSAX 1000, PSAX 2300, or PSAX 4500 chassis. Use of the locking tab is not required for the PSAX 1250 chassis.
5 For new installations, run the cabling through a cable management system
that provides the necessary connector/cable strain relief to prevent damage to the I/O module connectors.

WARNING:
!To prevent any damage to the I/O module connectors, do not allow network cables to hang unaided from the connectors. Use standard cable installation procedures to run and secure the network cables through an appropriate cable management system before connecting the cables to the I/O modules.
End
Verifying the Initial Startup
After you insert the 1-Port DS3 IMA module into the chassis, observe the LED status indicators as described in Table 3. If the status indicators do not appear to function properly, refer to “Troubleshooting the Installation” on page 7.
Table 3. LED Indicators for the 1-Port DS3 IMA Module
Initial Power-On No Configured Ports One or More Configured Ports No Cable on Port Cable on Port FAIL (red) Lights briefly1
Not lit Lights only when the module is not func-tioning N/A N/A ACTIVE (green) Lights briefly1
Not lit Lights only when the module is function-ing prop-erly N/A N/A LOS [Loss of Signal] (yellow) Lights briefly2
N/A N/A Lights • Does not light if sig-nal is being received • Lights if signal is missing
1Note: After power is initially applied to the system and the system boot is
complete, the FAIL and ACTIVE LEDs indicate whether the module has no configured ports (red), or one or more configured ports (green).
2Note: After power is initially applied to the system and the system boot is
complete, this loss of signal LED indicates whether the port has a cable con-nected to it.

Removing the Module
Read the PacketStar®PSAX Safety Guidelines, which accompanies this product,
before proceeding.
WARNING:
!Be sure to use the ejector handles during installation and removal of a PSAX module.
1 Disconnect the cables from the module port (or ports).
2 Insert a flathead screwdriver into the screwdriver slot of the locking tab, and
slide the locking tab up and out of the locking tab slot (see Figure 3).
3 Pull backward on the ejector handle until the module is released from the
backplane.
4 Remove the module from the chassis.
5 Put the module in its ESD bag, close the bag, and place the module in its
orig-inal shipping box.
6 If another module is not being immediately inserted into the empty slot,
insert a blank faceplate module into the slot to prevent electromagnetic inter-ference (EMI) and maintain proper air flow inside the chassis.
!
CAUTION:
Ultimate disposal of this product should be handled according to all laws and regulations in your specific geographic region.
