Chapter 2. Unpacking and Checking the Shipping Group
This chapter describes the contents of the I/O card shipping groups, and describes how
to unpack the I/O cards.
Shipping Group Contents
E1/T1/J1 I/O Card or E1/T1/J1 IMA I/O Card
When you receive your I/O card, the shipping group for each card contains:
One I/O card, to be installed on the motherboard
One Vital Product Data (VPD) Programmable Read Only Memory (PROM) chip, to
be installed on the motherboard
Six screws to secure the I/O card to the motherboard
Two screwlock kits, one for each port
One faceplate
Two 'Y' cables for connecting up to 4 ports per I/O card. For the 8265, there are
two sets of 'Y' cables, one set for twisted pair connections and one set for coaxial
connections.
E3, DS3, OC3, and STM1 I/O Cards
When you receive your I/O card, the shipping group for each card contains:
One I/O card, to be installed on the motherboard
One Vital Product Data (VPD) Programmable Read Only Memory (PROM) chip, to
be installed on the motherboard.
Five screws: three for attaching the I/O card to the motherboard, and two for
securing the I/O card to the front panel of the module.
One motherboard faceplate bracket.
One dummy port cover with screw, for use when only one I/O card is installed on a
motherboard.
 Copyright IBM Corp. 1996, 1998 3

Before Unpacking the I/O Card
Take the following precautions before unpacking the I/O card:
Do not remove the component from its anti-static shielding bag until you are ready
to use it. This avoids the possibility of having electrostatic discharge damage
static-sensitive devices on the component.
When possible, handle the component by its faceplates.
Always use a foot strap and grounded mat or wear a grounded static discharge
wrist strap whenever you inspect or handle a component. Or else, be sure to
touch a grounded rack or another source of ground before handling it.
Ensure that you have a clean surface available on which to place the component.
Unpacking the Module or I/O Cards
When unpacking the I/O card, follow these steps:
1Verify that the I/O card is the correct model by comparing the Feature
Code listed on the side of the shipping carton with the Feature Code you
ordered.
2Remove the I/O card from its shipping carton.
3Remove the I/O card from its anti-static bag and inspect it for damage.
Always handle it by the faceplate being careful not to touch the internal
components.
Be sure to keep the screws that come with the I/O card as you will need
them to install the card on the motherboard.
If the I/O card appears to be damaged, put it back in the anti-static bag,
and put the bag back into the shipping carton. Then contact your local IBM
dealer.
IBM suggests that you keep the shipping carton and the anti-static shielding bags in
which the I/O card was delivered in case you later want to repackage it for storage or
shipment.
IBM also suggests that you record the serial number of the I/O card and other
information about the modules, and keep safely with your WAN module details.

Chapter 3. Installing an E1/T1/J1 or E1/T1/J1 IMA I/O Card
This chapter describes the steps required to install an E1/T1/J1 or E1/T1/J1 IMA I/O
card
Procedure
1Adjust the port jumpers on the I/O card to correspond to the type of
connection you will be using (E1 Coaxial, E1 Twisted-Pair, T1/J1
Twisted-Pair) by following the instructions in “Setting the Connection
Jumpers” on page 8.
2Ensure that the configuration of the grounding jumpers on the I/O card
conforms to the type of port connection and to the specific grounding
regulations in your country by following the instructions in “Setting the
Grounding Jumpers” on page 9.
3Mount the I/O card on the module by following the instructions in “Mounting
an E1/T1/J1 or E1/T1/J1 IMA on the Motherboard” on page 10.
4Configure the I/O card as described in the WAN Module User's Guide .
Note: If you replace an I/O card after configuring the module, the new
card is automatically configured with the settings of the previous card when
you re-insert the module.

Setting the Connection Jumpers
Each E1/T1/J1 and E1/T1/J1 IMA I/O card has four Port Connection jumpers (JP1-JP4;
see Figure 1 on page 6 and Figure 2 on page 7), which determine the types of
connection you can attach to each of the ports:
E1 Coaxial Connection
E1 Twisted-Pair Connection
T1/J1 Twisted-Pair Connection
Note: All ports on the same I/O card must be set up either:
All as T1/J1 connections (twisted-pair), or
All as E1 connections (any combination of coaxial or twisted-pair)
If E1 and T1/J1 connections are mixed on the same I/O card, NOT SUPPORTED PORT will
be displayed.
Figure 3 shows the correct position of the jumper for each connection type.

Setting the Grounding Jumpers
E1 and T1/J1 Twisted-Pair Connections
Twisted-pair connections should not be grounded. You must remove the grounding
jumpers from both the Transmit and the Receive jumper pins for each port that has a
twisted-pair connection.
E1 Coaxial Connections
Regulations governing the grounding of outer conductors on E1 coaxial pairs vary from
country to country. To conform to these country-specific regulations, eight jumpers
(one for Transmit and one for Receive on each port) are provided on the rear of the
E1/T1/J1 and E1/T1/J1 IMA I/O cards (see Figure 1 on page 6 and Figure 2 on
page 7)
If a jumper is inserted over a pair of jumper pins, the outer connector of the
corresponding port is grounded to the Frame Ground.
If no jumper is inserted, the outer connector of that port is grounded through a 10
nF capacitor.
Normally, only the outer connector of the transmit port is to be grounded, and not the
receive port. This depends on individual country regulations. Check to see whether
your country also requires the receive port to be grounded.
Note: Standard G.703 recommends that the outer conductor of the coaxial pair be
connected to ground on the transmit port, and that the same provision be available for
the receive port. Some countries however, have different rules, so the setting may be
not apply.

Chapter 3. Installing an E1/T1/J1 or E1/T1/J1 IMA I/O Card 9

Mounting an E1/T1/J1 or E1/T1/J1 IMA on the Motherboard
Attention: When installing an I/O card on the motherboard, be careful not to touch the
I/O card components. Always hold the card by its edges.
To mount the E1/T1/J1 I/O card or E1/T1/J1 IMA I/O Card on the motherboard, follow
these steps:
1Before mounting the I/O card on the motherboard, you must first isolate
and then remove the module from the IBM 8260 Nways Multiprotocol
Switching Hub, IBM 8285 Nways ATM Workgroup Switch, or IBM 8265
Nways ATM Switch. To isolate the module, enter the following command
from the ATM console:
SET MODULE slot ISOLATED
where slot specifies the number of the slot to be used.
2Detach the motherboard on which you want to install the I/O card by
removing the four screws (.1/ and .2/ in Figure 4) that hold the
motherboard to the module. Save the screws in order to reattach the
motherboard.
