Positioning Multi-Bay Configurations

Preparing to Anchor Bays

Positioning procedures for the Series II bays are outlined in this chapter. When installing Series II bays in either 2 or 4-bay Configurations, refer to the "Terabit Switch Router Series II Install Guide" for specific instructions on anchoring procedures.

Due to its weight when fully loaded, the TSR Series II systems require sufficient anchoring to maintain fault tolerance through earthquakes and to ensure against tipping.

For more information on dimensions, weights, and floor loading refer to the "Terabit Switch Router Series II Install Guide."

TSR II 2-Bay and 4-Bay Configurations

In TSR II multi-bay configurations, there is no distinction between the bay types. Figure 2-1 shows a 2-bay buildout (front bays) of TSR II bays and a 4-bay buildout (front and rear bays) of four TSR II bays.

Figure 2-1. Configuration Buildout
In TSR II 2-bay configurations, the design of the TSR II allows side-by-side installation without side panel removal.

Determining Space Requirements - TSR II Bays

In planning for installation, ensure that sufficient space is allowed both for moving and positioning the bays as well as for installation. For 2-bay installations, the bays are positioned side-by-side (refer to Figure 2-2).

NOTE When planning for multibay installations, allow sufficient access space between back-to-back rows. This means always including the measurements of the rear EMI covers as well as the bay in determining floor space planning.

Adjusting the Alignment of TSR Bays

With all of the connection bolts now engaged, recheck that the cabinet is vertically aligned, side-to-side and front-to-rear within 0.25 cm (0.1 in.) of the Bay 1.

Concrete and Pedestal Installations

PROCEDURE: Use the following procedure to level and complete the anchoring of the additional bay to the floor or pedestal:

Step 1 To set the height and alignment of the bay, select and insert the final shims by:

Checking the level or alignment to the installed bay.

Confirming that tops of the bays should be at the same height and vertical posts are flush, both front and rear.

Adjusting the dolly height to lift the bay for shim insertion.

Adding shims as needed to each of the four corners to ensure the bay is even in height and the vertical posts are flush from top to bottom with the existing bay.

Adding shims to the outer corners if the gap is larger at the top of the vertical post. Add shims to the inner posts if the gap is larger at the bottom.

NOTE The recommended maximum height for shims is 13 mm (0.5 in.). The absolute maximum height for the shims is 19 mm (0.75 in.).

Step 2 Remove the custom dolly and levelers on the bottom of the TSR bay before tightening the anchors.

Step 3 Check that the bays are even in height and flush side to side.

Step 4 If necessary, tap the anchor bolt until it is fully seated on the washer stack-up.

NOTE The anchor bolt must be fully seated prior to tightening. If the bolt is tightened prior to fully seating the bolt, the expansion cone expands preventing further insertion of the anchor bolt.

Step 5 Using a 24 mm socket and ratchet handle, tighten the anchor bolts sequentially until the torque-limiting caps on the bolts snap off.

Raised Floor Installation without Pedestals

PROCEDURE: Use the following procedure to level and complete the anchoring of the additional bay to the floor:

Step 1 Check that the bay is virtually aligned, side-to-side, and front-to-rear within 0.25 cm (0.01 in.) of the bay height, using a spirit level or a plumb tool at the top of the frame. If the bay is not aligned insert shims as follows:

Adjust the custom dolly to slightly lift the bay enough to insert shims under the four corners as needed, then lower the bay until it is resting on the shims.

Check the bay again for alignment.

Continue raising and lowering the bay to add shims until correctly aligned.

Remove the custom dolly from the bay before tightening the anchor nuts.

Step 2 Remove the custom dollies from the frame before tightening the anchor nuts.

Step 3 Install nuts onto each of the four threaded rods, and using a 19 mm socket and torque wrench, torque the four nuts to 22 ft lb.

Tightening the Connection Bolts

With the Bay 3 now anchored and level in position, use the following procedure to complete tightening the connection bolts connecting the TSR bays:

Step 1 Use the 19 mm socket and torque wrench with extension to torque the bottom rear connection bolt to 60 ft lb + 2.

Step 2 Use the 19 mm socket and torque wrench with extension to torque the bottom front connection bolt to 60 ft lb + 2.

Step 3 Use the 19mm socket and torque wrench to torque the front and rear top connection plate bolts to 60 ft lb + 2.

Connecting Bays - TSR/TSR II 4-Bay Configuration

The 4-bay configuration extends the 2-bay configuration by adding 2 bays behind the existing 2 bays in a back-to-back row. The rear bay frames connect bay with connection bolts and connector brackets. Connection bolts slide through the connection holes in Bay 2 into threaded holes in Bay 4 only on the bottom of the TSR II bays.

After anchoring bay 2, and engaging the connection bolts through the bottom bolt holes in Bay 4, connector brackets are installed and the bays are aligned. Refer to "Adjusting the Alignment of the Bays". After the bays are aligned, the anchor bolts are fully tightened. Refer to the "Terabit Switch Router Series II Install Guide" for completing the anchoring procedure. After completing anchoring, the connection bolts in the bay frames and in the connector brackets are fully tightened to secure the TSR II bay frames together.

PROCEDURE: Beginning at the bottom rear connection bolt hole in Bay 2, use the following procedure to insert the connection bolts:

Step 1 Place the lock washer and flat washer on a M12x60 connection bolt and slide the bolt through the bottom rear connection through hole in Bay 2 and begin to engage the bolt in the threaded hole of Bay 4 (refer to Figure 2-41).

Rotary and Toggle Switch Settings

The toggle and rotary switch settings on the TSR bay backplanes identify the location of each bay in the lineup. The toggle switch identifies where (i.e., front or back row) and the rotary switch number identifies the bay's number within the front or back row (refer to Figure 2-45).

The toggle and rotary switches are located on the bay controller backplane of each TSR and TSR II bay. Refer to Figure 2-46. The toggle switch specifies whether this bay is in the front or back row (F or B). The rotary switch specifies the number of the bay within the front or rear row in a multiple bay lineup (refer to Figure 2-46).

NOTE In TSR bays, front on the toggle switch indicates "front." In TSR II bays, front on the toggle switch is indicated by the numeral "0."
