Completing the Installation

3.Tighten the two screws on the RJ21 straight cable connector or RJ21 angle adapter, as applicable, to secure it to the device.

NOTE

The cable pinouts for a 25-pair cable (RJ21) can be found in the Cabletron Systems Cabling Guide. Refer to Section 1.2 for details on how to obtain this document.

4.If using the RJ21 angle adapter, plug the RJ21 right-angled connector as shown in Figure 3-7. Depending on the type of RJ21 cable connector, it can be either plugged in until the retaining clips on the RJ21 adapter/extender snap into place or secured with screws.

5.Use the Group Select button to step to Group 1, 2, 3, or 4 and check LED pairs 1 through 12 to determine their link status. The top LEDs are the RX LEDs and the bottom ones are the TX LEDs. Start by stepping to Group 1 and verify that a link exists on each twisted pair segment of the RJ21 (Group 1) connector by checking to see if the associated port RX LED is on (flashing amber, blinking green, or solid green). Figure 3-6shows the RX and TX LEDs for port 1 of Group 1. If any of the RX LEDs are off, perform the following steps to check the associated twisted pair segment. The problem is resolved when the Link LED comes on.

a.Verify that the device at the other end of the twisted pair segment is on and connected to the segment.

b.Verify that the RJ21 connector associated with the twisted pair segment has the proper pinouts and check the cable for continuity.

c.Check that the twisted pair connection meets the dB loss and cable specifications outlined in Chapter 2.

If a link is not established, contact Cabletron Systems. Refer to Section 1 for details.

6.Repeat steps 1 through 5 until all connections are made.

3.5COMPLETING THE INSTALLATION

After installing the 2E253-49R and any optional HSIM or VHSIM, and making the connections to the network, proceed as follows:

1.Secure the cables by running the cables along the strain-relief bracket and tying them to the strain-relief bracket using cable ties.

2.The 2E253-49R is now ready to be configured through Local Management. Refer to the SmartSwitch Series 2E253, 2H252, 2H253, and 2H258 Local Management User’s Guide for information on how to access and use Local Management.
